+# This is a way to override platform detection, e.g. when you're running
+# a Ubuntu derivative based on 18.04, you could do:
+#
+# platform-override:
+#   arch: A_64
+#   platform:
+#     contents: Ubuntu
+#     tag: Linux
+#   version: '18.04'
+platform-override: null
+
+# Support for mirrors. Currently there are 3 hosts you can mirror:
+#   - github.com (for stack and some older HLS versions)
+#   - raw.githubusercontent.com (for the yaml metadata)
+#   - downloads.haskell.org (for everything else)
+#
+# E.g. when we have 'https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-0.0.7.yaml'
+# and the following mirror config
+#
+#  "raw.githubusercontent.com":
+#    authority:
+#      host: "mirror.sjtu.edu.cn"
+#    pathPrefix: "ghcup/yaml"
+#
+# Then the resulting url will be 'https://mirror.sjtu.edu.cn/ghcup/yaml/haskell/ghcup-metadata/master/ghcup-0.0.7.yaml'
+mirrors:
+  "github.com":
+    authority:
+      host: "mirror.sjtu.edu.cn"
+  "raw.githubusercontent.com":
+    authority:
+      host: "mirror.sjtu.edu.cn"

+## Distribution policies
+
+Like most Linux distros and other distribution channels, GHCup also
+follows certain policies. These are as follows:
+
+1. The end-user experience is our primary concern
+    - ghcup in CI systems as a use case is a first class citizen
+2. We strive to collaborate with all maintainers of all the tools we support and maintain a good relationship
+3. We may fix build system or other distribution bugs in upstream bindists
+    - these are always communicated upstream
+4. We may even patch source code of supported tools in very rare cases if that is required to ensure that the end-user experience does not break
+    - we'll first try to upstream any such required patch and request a new release to avoid downstream patching
+    - patches will be communicated to the maintainers either way and we'll strive to get their review
+    - they will also be communicated to the end-user
+    - they will be uploaded along with the bindist
+    - we will avoid maintaining long-running downstream patches (currently zero)
+5. We may add bindists for platforms that upstream does not support
+    - this is currently the case for GHC for e.g. Alpine and possibly FreeBSD in the future
+    - this is currently also the case for stack on darwin M1
+    - we don't guarantee for unofficial bindists that the test suite passes at the moment (this may change in the future)
+6. We GPG sign all the GHCup metadata as well as the unofficial bindists

 2. Update `GHCup.Version` module. `ghcupURL` must only be updated if we change the `GHCupInfo` type or the YAML representation of it. The version of the YAML represents the change increments. `ghcUpVer` is the current application version, read from `ghcup.cabal`.
 
 3. Add ChangeLog entry

Generally, new GHC/cabal/stack/hls versions are only added to the latest yaml file. New GHCup versions are added to all (great care must be taken here to not break the parser... e.g. ARM platforms don't parse in all older formats).
+4. If a new ghcup yaml version is needed, create one at [ghcup-metadata repo](https://github.com/haskell/ghcup-metadata) and push to a temporary release branch, then update the `data/metadata` submodule in ghcup-hs repo to that branch, so CI can pass

-## Configuration
+### Tags and shortcuts
+
+GHCup has a number of tags and version shortcuts, that can be used as arguments to **install**/**set** etc.
+All of the following are valid arguments to `ghcup install ghc`:
+
+* `latest`, `recommended`
+* `base-4.15.1.0`
+* `9.0.2`, `9.0`, `9`
+
+If the argument is omitted, the default is `recommended`.
+
+Other tags include:
+
+- `prerelease`: a prerelease version
+- `latest-prerelease`: the latest prerelease version
+
+
+## Manpages
+
+For man pages to work you need [man-db](http://man-db.nongnu.org/) as your `man` provider, then issue `man ghc`. Manpages only work for the currently set ghc.
+`MANPATH` may be required to be unset.
+
+## Shell-completion
+
+Shell completions are in [scripts/shell-completions](https://github.com/haskell/ghcup-hs/tree/master/scripts/shell-completions) directory of this repository.
+
+For bash: install `shell-completions/bash`
+as e.g. `/etc/bash_completion.d/ghcup` (depending on distro)
+and make sure your bashrc sources the startup script
+(`/usr/share/bash-completion/bash_completion` on some distros).
+
+## Portability
+
+`ghcup` is very portable. There are a few exceptions though:
+
+1. legacy subcommands `ghcup install` (without a tool identifier) and `ghcup install-cabal` may be removed in the future
+
+# Configuration
 
 A configuration file can be put in `~/.ghcup/config.yaml`. The default config file
-explaining all possible configurations can be found in this repo: [config.yaml](https://gitlab.haskell.org/haskell/ghcup-hs/-/blob/master/data/config.yaml).

+## Overriding distro detection
+
+If you're running e.g. an Ubuntu derivative based on 18.04 and ghcup is picking bindists that
+don't work well, you could do this in `config.yaml`:

+
+## Env variables
+
+This is the complete list of env variables that change GHCup behavior:
+
+* `GHCUP_USE_XDG_DIRS`: see [XDG support](#xdg-support) below
+* `GHCUP_INSTALL_BASE_PREFIX`: the base of ghcup (default: `$HOME`)
+* `GHCUP_CURL_OPTS`: additional options that can be passed to curl
+* `GHCUP_WGET_OPTS`: additional options that can be passed to wget
+* `GHCUP_GPG_OPTS`: additional options that can be passed to gpg
+* `GHCUP_SKIP_UPDATE_CHECK`: Skip the (possibly annoying) update check when you run a command
+* `CC`/`LD` etc.: full environment is passed to the build system when compiling GHC via GHCup
+
+On windows, there's additionally:
+
+* `GHCUP_MSYS2`: Has to point to the root of an existing MSYS2 installation (when installed by GHCup, that's e.g. `C:\ghcup\msys64`). GHCup bootstrap takes care of this usually.
+
+### XDG support
+
+To enable XDG style directories, set the environment variable `GHCUP_USE_XDG_DIRS` to anything.
+
+Then you can control the locations via XDG environment variables as such:
+
+* `XDG_DATA_HOME`: GHCs will be unpacked in `ghcup/ghc` subdir (default: `~/.local/share`)
+* `XDG_CACHE_HOME`: logs and download files will be stored in `ghcup` subdir (default: `~/.cache`)
+* `XDG_BIN_HOME`: binaries end up here (default: `~/.local/bin`)
+* `XDG_CONFIG_HOME`: the config file is stored in `ghcup` subdir as `config.yaml` (default: `~/.config`)
+
+**Note that `ghcup` makes some assumptions about structure of files in `XDG_BIN_HOME`. So if you have other tools
+installing e.g. stack/cabal/ghc into it, this will likely clash. In that case consider disabling XDG support.**
+
+## Caching
+
+GHCup has a few caching mechanisms to avoid redownloads. All cached files end up in `~/.ghcup/cache` by default.
+
+### Downloads cache
+
+Downloaded tarballs (such as GHC, cabal, etc.) are not cached by default unless you pass `ghcup --cache` or set caching
+in your [config](#configuration) via `ghcup config set cache true`.
+
+### Metadata cache
+
+The metadata files (also see [github.com/haskell/ghcup-metadata](https://github.com/haskell/ghcup-metadata))
+have a 5 minutes cache per default depending on the last access time of the file. That means if you run
+`ghcup list` 10 times in a row, only the first time will trigger a download attempt.
+
+### Clearing the cache
+
+If you experience problems, consider clearing the cache via `ghcup gc --cache`.
+
+## Metadata
+
+Metadata files are also called release or distribution channels. They describe tool versions, where to download them etc. and
+can be viewed here: [https://github.com/haskell/ghcup-metadata](https://github.com/haskell/ghcup-metadata).
+
+See the [description](https://github.com/haskell/ghcup-metadata#metadata-variants-distribution-channels)
+of metadata files to understand their purpose. These can be combined.
+
+For example, if you want access to both prerelease and cross bindists, you'd do:
+
+```sh
+ghcup config add-release-channel https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.7.yaml
+ghcup config add-release-channel https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-cross-0.0.8.yaml
+```
+
+This results in the following configuration in `~/.ghcup/config.yaml`:
+
+```yaml
+url-source:
+# the base url that contains all the release bindists
+- GHCupURL
+# prereleases
+- https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.8.yaml
+# cross bindists
+- https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-cross-0.0.8.yaml
+```
+
+You can add as many channels as you like. They are combined under *Last*, so versions from the prerelease channel
+here overwrite the default ones, if any.
+
+To remove the channel, delete the entire `url-source` section or set it back to the default:
+
+```yml
+url-source:
+  - GHCupURL
+```
+
+Also see [config.yaml](https://github.com/haskell/ghcup-hs/blob/master/data/config.yaml)
+for more options.
+
+You can also use an alternative metadata via one-shot cli option:
+
+```sh
+ghcup --url-source=https://some-url/ghcup-0.0.8.yaml tui
+```
+
+One main caveat of using URLs is that you might need to check whether there are new versions
+of the file (e.g. `ghcup-0.0.7.yaml` vs `ghcup-0.0.8.yaml`). Although old metadata files
+are supported for some time, they are not so indefinitely.
+
+### Mirrors
+
+Metadata files can also be used to operate 3rd party mirrors, in which case you want to use
+a URL instead of the `GHCupURL` alias. E.g. in `~/.ghcup/config.yaml`, you'd do:
+
+```yml
+url-source:
+  - https://mirror.sjtu.edu.cn/ghcup/yaml/ghcup/data/ghcup-0.0.6.yaml
+```
+
+Note that later versions of GHCup allow more sophisticated mirror support, see [here](./#mirrors-proper).
+
+#### Known mirrors
+
+1. [https://mirror.sjtu.edu.cn/docs/ghcup](https://mirror.sjtu.edu.cn/docs/ghcup)
+2. [https://mirrors.ustc.edu.cn/help/ghcup.html](https://mirrors.ustc.edu.cn/help/ghcup.html)
+
+### Git based metadata config
+
+If you don't like the way ghcup updates its metadata with caching and fetching via curl, you can also do as follows:
+
+Clone the metadata git repo:
+
+```sh
+mkdir -p /home/user/git/
+cd /home/user/git/
+git clone -b master https://github.com/haskell/ghcup-metadata.git
+```
+
+Then tell ghcup to use file locations in `~/.ghcup/config.yaml`, e.g.:
+
+```yaml
+url-source:
+- file:///home/user/git/ghcup-metadata/ghcup-0.0.8.yaml
+- file:///home/user/git/ghcup-metadata/ghcup-cross-0.0.8.yaml
+- file:///home/user/git/ghcup-metadata/ghcup-prereleases-0.0.8.yaml
+```
+
+Now, if you invoke `ghcup tui`, it will open instantly without any download, since it just
+reads the metadata from local disk.
+
+You'll have to update the metadata manually though, like so:
+
+```sh
+cd /home/user/git/
+git pull --ff-only origin master
+```
+
+## Stack integration
+
+Stack manages GHC versions internally by default. In order to make it use ghcup installed
+GHC versions there are two strategies.
+
+### Strategy 1: Stack hooks (new, recommended)
+
+Since stack 2.9.1 you can customize the installation logic of GHC completely, see [https://docs.haskellstack.org/en/stable/yaml_configuration/#ghc-installation-customisation](https://docs.haskellstack.org/en/stable/yaml_configuration/#ghc-installation-customisation).
+
+We can use this to simply invoke ghcup whenever stack is trying to install/discover a GHC versions. This
+is done via placing a shell script at `~/.stack/hooks/ghc-install.sh` and making it executable.
+
+The ghcup bootstrap script asks you during installation whether you want to install this shell script. You can also
+install/update it manually like so:
+
+```sh
+mkdir -p ~/.stack/hooks/
+curl https://raw.githubusercontent.com/haskell/ghcup-hs/master/scripts/hooks/stack/ghc-install.sh \
+  > ~/.stack/hooks/ghc-install.sh
+chmod +x ~/.stack/hooks/ghc-install.sh
+# hooks are only run when 'system-ghc: false'
+stack config set system-ghc false --global
+```
+
+By default, when the hook fails for whatever reason, stack will fall back to its own installation logic. To disable
+this, run `stack config set install-ghc false --global`.
+
+### Strategy 2: System GHC (works on all stack versions)
+
+You can instruct stack to use "system" GHC versions (whatever is in PATH). To do so,
+run the following commands:
+
+```sh
+stack config set install-ghc false --global
+stack config set system-ghc  true  --global
+```
+
+### Using stack's setup-info metadata to install GHC
+
+You can now use stack's [setup-info metadata](https://github.com/commercialhaskell/stackage-content/blob/master/stack/stack-setup-2.yaml)
+to install GHC. For that, you can invoke ghcup like so as a shorthand:
+
+```sh
+# ghcup will only see GHC now
+ghcup -s StackSetupURL install ghc 9.4.7
+# this combines both ghcup and stack metadata
+ghcup -s '["GHCupURL", "StackSetupURL"]' install ghc 9.4.7
+```
+
+To make this permanent and combine it with the GHCup metadata, you can add the following to your `~/.ghcup/config.yaml`:
+
+```yaml
+url-source:
+  - GHCupURL
+  # stack versions take precedence
+  # you'll still have access to GHCup provided versions and tools in case they don't exist in stack metadata
+  - StackSetupURL
+```
+
+You can customize or add sections to the setup-info similar to how the [stack documentation](https://docs.haskellstack.org/en/stable/yaml_configuration/#setup-info) explains it. E.g. to change the 9.4.7 bindist, you might do:
+
+```yaml
+url-source:
+  - GHCupURL
+  - StackSetupURL
+  - setup-info:
+      ghc:
+        linux64-tinfo6:
+          9.4.7:
+            url: "https://downloads.haskell.org/~ghc/9.4.7/ghc-9.4.7-x86_64-fedora27-linux.tar.xz"
+            content-length: 179117892
+            sha256: 216b76b7c6383e6ad9ba82533f323f8550e52893a8b9fa33c7b9dc4201ac766a
+```
+
+#### Caveats
+
+The main caveat with using this method is that there's no guarantee that GHCup will pick a compatible HLS bindist
+when you try to install HLS.
+
+Another potential usability issue is that the `latest` and `recommended` shorthands won't work anymore, since
+Stack metadata doesn't have a concept of those and we don't try to be smart when combining the metadatas.
+
+### Windows
+
+On windows, you may find the following config options useful too:
+`skip-msys`, `extra-path`, `extra-include-dirs`, `extra-lib-dirs`.
+
+Also check out: [https://docs.haskellstack.org/en/stable/yaml_configuration](https://docs.haskellstack.org/en/stable/yaml_configuration)
+
+## Mirrors (proper)
+
+Mirrors are now supported via configuration, instead of specifying alternative metadata files.
+
+As an example, this would be a complete mirror configuration in `~/.ghcup/config.yaml`:
+
+```yaml
+mirrors:
+  # yaml download location, would result in:
+  #      https://raw.githubusercontent.com/haskell/ghcup-metadata/develop/ghcup-0.0.8.yaml
+  #   -> https://mirror.sjtu.edu.cn/ghcup/yaml/haskell/ghcup-metadata/master/ghcup-0.0.8.yaml
+  "raw.githubusercontent.com":
+    authority:
+      host: "mirror.sjtu.edu.cn"
+    pathPrefix: "ghcup/yaml"
+  # for stack and some older HLS versions, would result in e.g.
+  #      https://github.com/haskell/haskell-language-server/releases/download/1.2.0/haskell-language-server-Windows-1.2.0.tar.gz
+  #   -> https://mirror.sjtu.edu.cn/ghcup/github/haskell/haskell-language-server/releases/download/1.2.0/haskell-language-server-Windows-1.2.0.tar.gz
+  "github.com":
+    authority:
+      host: "mirror.sjtu.edu.cn"
+    pathPrefix: "ghcup/github"
+  # for all haskell.org hosted bindists, would result in e.g.
+  #      https://downloads.haskell.org/~ghc/9.8.1/ghc-9.8.1-x86_64-deb10-linux.tar.xz
+  #   -> https://mirror.sjtu.edu.cn/ghcup/haskell-downloads/~ghc/9.8.1/ghc-9.8.1-x86_64-deb10-linux.tar.xz
+  "downloads.haskell.org":
+    authority:
+      host: "mirror.sjtu.edu.cn"
+    pathPrefix: "downloads.haskell.org"
+```
+
+The configuration depends on the host of the mirror and they have to provide the correct configuration.
+
+# More on installation
+
+## Customisation of the installation scripts
+
+The scripts offered to install GHCup are available here:
+
+* [bootstrap-haskell](https://github.com/haskell/ghcup-hs/blob/master/scripts/bootstrap/bootstrap-haskell#L7)
+  for Unix-like operating systems
+* [bootstrap-haskell.ps1](https://github.com/haskell/ghcup-hs/blob/master/scripts/bootstrap/bootstrap-haskell.ps1)
+  for Windows (PowerShell). This will, in turn, run the final bootstrap script
+  (by default, that for the Unix-like operating systems).
+
+The effect of the scripts can be customised by setting one or more
+`BOOTSTRAP_HASKELL_*` environment variables (as set out in the first script)
+and, in the case of Windows, by specifying parameters (as set out in the
+PowerShell script).
+
+For example, you can toggle:
+
+* non-interactive installation
+* a more verbose installation
+* whether to install only GHCup (and, on Windows, MSYS2)
+* not to trigger the upgrade of GHCup
+* whether to install the latest version of HLS
+* whether to install the latest version of Stack
+* whether to respect the XDG Base Directory Specification
+* whether to adjust (prepend) the PATH in `bashrc`
+* on Windows, whether to adjust MINGW paths in `cabal.config`
+
+You can also specify:
+
+* the GHC version to install
+* the Cabal version to install
+* which downloader to use (the default is `curl`)
+* the base URL for the download of the GHCup binary distribution
+
+On Windows, you can also use the parameters to:
+
+* toggle whether to overwrite a previous installation
+* specify the GHCup installation root directory
+* specify the Cabal root directory
+* specify the directory of an existing installation of MSYS2 (for example,
+  the one supplied by Stack)
+* specify the URL of the final bootstrap script
+* toggle whether to run the final bootstrap script via `bash` (instead of in a
+  new MSYS2 shell)
+
+## Installing custom bindists
+
+There are a couple of good use cases to install custom bindists:
+
+1. manually built bindists (e.g. with patches)
+    - example: `ghcup install ghc -u 'file:///home/mearwald/tmp/ghc-eff-patches/ghc-8.10.2-x86_64-deb10-linux.tar.xz' 8.10.2-eff`
+2. GHC head CI bindists
+    - example specifying a branch (`master`): `ghcup install ghc -u 'https://gitlab.haskell.org/ghc/ghc/-/jobs/artifacts/master/raw/ghc-x86_64-linux-fedora33-release.tar.xz?job=x86_64-linux-fedora33-release' head`
+    - example specifying a job id (`1129565`): `ghcup install ghc -u ' https://gitlab.haskell.org/api/v4/projects/1/jobs/1129565/artifacts/ghc-x86_64-linux-alpine3_12-validate+fully_static.tar.xz' mr7847`
+3. DWARF bindists
+    - example: `ghcup install ghc -u 'https://downloads.haskell.org/~ghc/8.10.2/ghc-8.10.2-x86_64-deb10-linux-dwarf.tar.xz' 8.10.2-dwarf`
+
+Since the version parser is pretty lax, `8.10.2-eff` and `head` are both valid versions
+and produce the binaries `ghc-8.10.2-eff` and `ghc-head` respectively.
+GHCup always needs to know which version the bindist corresponds to (this is not automatically
+detected).
+
+## Compiling from source
+
+### GHC
+
+Compiling from source is supported for both source tarballs and arbitrary git refs. See `ghcup compile ghc --help`
+for a list of all available options.
+
+If you need to overwrite the existing `build.mk`, check the default files
+in [data/build_mk](https://github.com/haskell/ghcup-hs/tree/master/data/build_mk), copy them somewhere, adjust them and
+pass `--config path/to/build.mk` to `ghcup compile ghc`.
+Common `build.mk` options are explained [here](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/using#build-configuration).
+
+Make sure your system meets all the [prerequisites](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/preparation).
+
+### HLS
+
+There are 3 main ways to compile HLS from source.
+
+1. from hackage (should have up to date version bounds)
+    - `ghcup compile hls --version 1.7.0.0 --ghc 9.2.3`
+2. from git (allows to build latest sources and PRs)
+    - `ghcup compile hls --git-ref master --ghc 9.2.3`
+    - `ghcup compile hls --git-ref a32db0b --ghc 9.2.3`
+    - `ghcup compile hls --git-ref 1.7.0.0 --ghc 9.2.3`
+3. from source distribution that's packaged during release from the corresponding git sources
+    - `ghcup compile hls --source-dist 1.7.0.0 --ghc 9.2.3`
+
+All these use `cabal v2-install` under the hood, so all build components are cached.
+You can pass arbitrary arguments to cabal, e.g. set the index state like so:
+
+```sh
+ghcup compile hls --git-ref master --ghc 9.2.3 -- --index-state=2022-06-12T00:00:00Z --allow-newer
+```
+
+You can pass `--ghc <ver>` multiple times to install for many GHCs at once.
+
+When building from git sources, ghcup will auto-detect the HLS version that the git commit corresponds to
+from the `haskell-language-server.cabal` file. This version might not have been updated since the last release.
+If you want to avoid overwriting the existing installed HLS version, you can instruct ghcup to use `git describe`
+to set the HLS version instead:
+
+```sh
+ghcup compile hls --git-ref master --ghc 9.2.3 --git-describe-version
+```
+
+You can also set the version explicitly:
+
+```sh
+ghcup compile hls --git-ref master --ghc 9.2.3 --overwrite-version 1.7.0.0-p1
+```
+
+To instruct cabal to run `cabal update` before building, run `ghcup compile hls --version 1.7.0.0 --ghc 9.2.3 --cabal-update`
+
+As always, check `ghcup compile hls --help`.
+
+#### Updating HLS for a new GHC version
+
+First try to build from hackage with some tricks:
+
+```sh
+ghcup compile hls --version 1.7.0.0 --ghc 9.2.4 --cabal-update -- --allow-newer --index-state=2022-06-12T00:00:00Z
+```
+
+This augments the currently installed 1.7.0.0 official bindists in ghcup with new GHC versions support.
+
+If that fails (since `--allow-newer` is quite brutal), you can install from HLS master branch (which may contain new fixes) like so:
+```
+ghcup compile hls --git-ref master --git-describe-version --ghc 8.10.7 --ghc 9.2.4 --cabal-update
+```
+
+This however will create a new HLS version in ghcup, e.g. `1.7.0.0-105-gdc682ba1`, for both 8.10.7 and 9.2.4. If you want to switch back to the official bindists, run `ghcup set hls 1.7.0.0`.
+
+## Cross support
+
+ghcup can compile a cross GHC for any target. However, this
+requires that the build host has a complete cross toolchain and various
+libraries installed for the target platform.
+
+Consult the GHC documentation on the [prerequisites](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/cross-compiling#tools-to-install).
+For distributions with non-standard locations of cross toolchain and
+libraries, this may need some tweaking of `build.mk` or configure args.
+See `ghcup compile ghc --help` for further information.
+
+Since ghcup version 0.1.20.0, we provide cross bindists for GHC JS and WASM. These can be installed conveniently.
+However, these are intended as a developer preview only. By using these GHC variants, you are implicitly signing up to participate in GHC development!
+If you run into bugs or missing behavior, join the dev chat at https://matrix.to/#/#GHC:matrix.org. 
+
+First, add the cross release channel:
+
+```sh
+ghcup config add-release-channel https://raw.githubusercontent.com/haskell/ghcup-metadata/develop/ghcup-cross-0.0.8.yaml
+```
+
+The next sections explain how to install each cross bindist.
+
+### GHC JS cross bindists (experimental)
+
+You need the required emscripten JS toolchain:
+
+```sh
+git clone https://github.com/emscripten-core/emsdk.git
+cd emsdk
+./emsdk install latest
+./emsdk activate latest
+source ./emsdk_env.sh
+```
+
+Instructions are also here: [Download and install — Emscripten 3.1.43-git (dev) documentation](https://emscripten.org/docs/getting_started/downloads.html).
+
+To install we need to invoke ghcup like so:
+
+```sh
+emconfigure ghcup install ghc --set javascript-unknown-ghcjs-9.6.2
+```
+
+You'll now have the compiler `javascript-unknown-ghcjs-ghc`. To build a hello world, do e.g.:
+
+```sh
+echo 'main = putStrLn "hello world"' > hello.hs
+javascript-unknown-ghcjs-ghc -fforce-recomp hello.hs
+./hello
+```
+
+You can follow the instructions [here](https://gitlab.haskell.org/ghc/ghc/-/wikis/javascript-backend/building#compiling-hello-world).
+
+### GHC WASM cross bindists (experimental)
+
+You need the required wasm toolchain:
+
+```sh
+git clone https://gitlab.haskell.org/ghc/ghc-wasm-meta.git
+cd ghc-wasm-meta/
+export SKIP_GHC=yes
+./setup.sh
+source ~/.ghc-wasm/env
+```
+
+To install, we need to invoke ghcup like so also passing the `--host=<host>` flag (adjust as needed):
+
+```sh
+ghcup install ghc --set wasm32-wasi-9.6.3.20230927 -- --host=x86_64-linux --with-intree-gmp --with-system-libffi
+```
+
+Also check the documentation here: [Glasgow Haskell Compiler / ghc-wasm-meta](https://gitlab.haskell.org/ghc/ghc-wasm-meta).
+
+You'll now have the compiler `wasm32-wasi-ghc`. To build a hello world, do e.g.:
+
+```sh
+echo 'main = putStrLn "hello world"' > hello.hs
+wasm32-wasi-ghc hello.hs -o hello.wasm
+wasmtime ./hello.wasm
+```
+
+## Isolated installs
+
+**Before using isolated installs, make sure to have at least GHCup version 0.1.17.8!**
+
+Ghcup also enables you to install a tool (GHC, Cabal, HLS, Stack) at an isolated location of your choosing.
+These installs, as the name suggests, are separate from your main installs and DO NOT conflict with them.
+
+
+- No symlinks are made to these isolated installed tools, you'd have to manually point to them wherever you intend to use them.
+
+- These installs, can also NOT be deleted from ghcup, you'd have to go and manually delete these.
+
+You need to use the `--isolate` or `-i` flag followed by the directory path.
+
+Examples:
+
+1. install an isolated GHC version at location /home/user/isolated_dir/ghc/
+    - `ghcup install ghc 8.10.5 --isolate /home/user/isolated_dir/ghc`
+
+2. isolated install Cabal at a location you desire
+    - `ghcup install cabal --isolate /home/username/my_isolated_dir/`
+
+3. do an isolated install with a custom bindist
+    - `ghcup install ghc --isolate /home/username/my_isolated_dir/ -u 'https://gitlab.haskell.org/ghc/ghc/-/jobs/artifacts/master/raw/ghc-x86_64-linux-fedora33-release.tar.xz?job=x86_64-linux-fedora33-release' head`
+
+4. isolated install HLS
+    - `ghcup install hls --isolate /home/username/dir/hls/`
+
+5. you can even compile ghc to an isolated location.
+    - `ghcup compile ghc -j 4 -v 9.0.1 -b 8.10.5 -i /home/username/my/dir/ghc`
+
+## Continuous integration
+
+On Windows, GHCup can be installed automatically on a CI runner
+non-interactively, as below. The parameters to the PowerShell script are
+specified positionally, after `-ArgumentList`:
+
+```ps
+$ErrorActionPreference = 'Stop';Set-ExecutionPolicy Bypass -Scope Process -Force;[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;try { Invoke-Command -ScriptBlock ([ScriptBlock]::Create((Invoke-WebRequest https://www.haskell.org/ghcup/sh/bootstrap-haskell.ps1 -UseBasicParsing))) -ArgumentList $false,$true,$true,$false,$false,$false,$false,"C:\" } catch { Write-Error $_ }
+```
+
+`$ErrorActionPreference = 'Stop'` here acts like `set -e` and stops execution if ghcup installation fails.
+
+On linux/darwin/freebsd, run the following on your runner:

 ## GPG verification
 
 GHCup supports verifying the GPG signature of the metadata file. The metadata file then contains SHA256 hashes of all downloads, so
 this is cryptographically secure.

-## Manpages
+# Tips and tricks
 
-For man pages to work you need [man-db](http://man-db.nongnu.org/) as your `man` provider, then issue `man ghc`. Manpages only work for the currently set ghc.
-`MANPATH` may be required to be unset.
+## ghcup run
 
-## Shell-completion
-
-Shell completions are in [scripts/shell-completions](https://gitlab.haskell.org/haskell/ghcup-hs/-/tree/master/scripts/shell-completions) directory of this repository.
-
-For bash: install `shell-completions/bash`
-as e.g. `/etc/bash_completion.d/ghcup` (depending on distro)
-and make sure your bashrc sources the startup script
-(`/usr/share/bash-completion/bash_completion` on some distros).
-
-## Compiling GHC from source
-
-Compiling from source is supported for both source tarballs and arbitrary git refs. See `ghcup compile ghc --help`
-for a list of all available options.
-
-If you need to overwrite the existing `build.mk`, check the default files
-in [data/build_mk](https://gitlab.haskell.org/haskell/ghcup-hs/-/tree/master/data/build_mk), copy them somewhere, adjust them and
-pass `--config path/to/build.mk` to `ghcup compile ghc`.
-Common `build.mk` options are explained [here](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/using#build-configuration).
-
-Make sure your system meets all the [prerequisites](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/preparation).
-
-### Cross support
-
-ghcup can compile and install a cross GHC for any target. However, this
-requires that the build host has a complete cross toolchain and various
-libraries installed for the target platform.
-
-Consult the GHC documentation on the [prerequisites](https://gitlab.haskell.org/ghc/ghc/-/wikis/building/cross-compiling#tools-to-install).
-For distributions with non-standard locations of cross toolchain and
-libraries, this may need some tweaking of `build.mk` or configure args.
-See `ghcup compile ghc --help` for further information.
-
-## XDG support
-
-To enable XDG style directories, set the environment variable `GHCUP_USE_XDG_DIRS` to anything.
-
-Then you can control the locations via XDG environment variables as such:
-
-* `XDG_DATA_HOME`: GHCs will be unpacked in `ghcup/ghc` subdir (default: `~/.local/share`)
-* `XDG_CACHE_HOME`: logs and download files will be stored in `ghcup` subdir (default: `~/.cache`)
-* `XDG_BIN_HOME`: binaries end up here (default: `~/.local/bin`)
-* `XDG_CONFIG_HOME`: the config file is stored in `ghcup` subdir as `config.yaml` (default: `~/.config`)
-
-**Note that `ghcup` makes some assumptions about structure of files in `XDG_BIN_HOME`. So if you have other tools
-installing e.g. stack/cabal/ghc into it, this will likely clash. In that case consider disabling XDG support.**
-
-## Env variables
-
-This is the complete list of env variables that change GHCup behavior:
-
-* `GHCUP_USE_XDG_DIRS`: see [XDG support](#xdg-support) above
-* `TMPDIR`: where ghcup does the work (unpacking, building, ...)
-* `GHCUP_INSTALL_BASE_PREFIX`: the base of ghcup (default: `$HOME`)
-* `GHCUP_CURL_OPTS`: additional options that can be passed to curl
-* `GHCUP_WGET_OPTS`: additional options that can be passed to wget
-* `GHCUP_GPG_OPTS`: additional options that can be passed to gpg
-* `GHCUP_SKIP_UPDATE_CHECK`: Skip the (possibly annoying) update check when you run a command
-* `CC`/`LD` etc.: full environment is passed to the build system when compiling GHC via GHCup
-
-## Installing custom bindists
-
-There are a couple of good use cases to install custom bindists:
-
-1. manually built bindists (e.g. with patches)
-    - example: `ghcup install ghc -u 'file:///home/mearwald/tmp/ghc-eff-patches/ghc-8.10.2-x86_64-deb10-linux.tar.xz' 8.10.2-eff`
-2. GHC head CI bindists
-    - example: `ghcup install ghc -u 'https://gitlab.haskell.org/api/v4/projects/1/jobs/artifacts/master/raw/ghc-x86_64-fedora27-linux.tar.xz?job=validate-x86_64-linux-fedora27' head`
-3. DWARF bindists
-    - example: `ghcup install ghc -u 'https://downloads.haskell.org/~ghc/8.10.2/ghc-8.10.2-x86_64-deb10-linux-dwarf.tar.xz' 8.10.2-dwarf`
-
-Since the version parser is pretty lax, `8.10.2-eff` and `head` are both valid versions
-and produce the binaries `ghc-8.10.2-eff` and `ghc-head` respectively.
-GHCup always needs to know which version the bindist corresponds to (this is not automatically
-detected).
-
-## Isolated installs
-
-Ghcup also enables you to install a tool (GHC, Cabal, HLS, Stack) at an isolated location of your choosing.
-These installs, as the name suggests, are separate from your main installs and DO NOT conflict with them.
-
-
-- No symlinks are made to these isolated installed tools, you'd have to manually point to them wherever you intend to use them.
-
-- These installs, can also NOT be deleted from ghcup, you'd have to go and manually delete these.
-
-You need to use the `--isolate` or `-i` flag followed by the directory path.
-
-Examples:
-
-1. install an isolated GHC version at location /home/user/isolated_dir/ghc/  
-    - `ghcup install ghc 8.10.5 --isolate /home/user/isolated_dir/ghc`
-
-2. isolated install Cabal at a location you desire  
-    - `ghcup install cabal --isolate /home/username/my_isolated_dir/`
-
-3. do an isolated install with a custom bindist  
-    - `ghcup install ghc --isolate /home/username/my_isolated_dir/ -u 'https://gitlab.haskell.org/api/v4/projects/1/jobs/artifacts/master/raw/ghc-x86_64-fedora27-linux.tar.xz?job=validate-x86_64-linux-fedora27' head`
-
-4. isolated install HLS  
-    - `ghcup install hls --isolate /home/username/dir/hls/`
-
-5. you can even compile ghc to an isolated location.  
-    - `ghcup compile ghc -j 4 -v 9.0.1 -b 8.10.5 -i /home/username/my/dir/ghc` 
-
-## Continuous integration
-
-On windows, ghcup can be installed automatically on a CI runner non-interactively like so:
-
-```ps
-Set-ExecutionPolicy Bypass -Scope Process -Force;[System.Net.ServicePointManager]::SecurityProtocol = [System.Net.ServicePointManager]::SecurityProtocol -bor 3072;Invoke-Command -ScriptBlock ([ScriptBlock]::Create((Invoke-WebRequest https://www.haskell.org/ghcup/sh/bootstrap-haskell.ps1 -UseBasicParsing))) -ArgumentList $false,$true,$true,$false,$false,$false,$false,"C:\"
-```
-
-On linux/darwin/freebsd, run the following on your runner:
+If you don't want to explicitly switch the active GHC all the time and are using
+tools that rely on the plain `ghc` binary, GHCup provides an easy way to execute
+commands with a certain toolchain prepended to PATH, e.g.:
 
 ```sh
-curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | BOOTSTRAP_HASKELL_NONINTERACTIVE=1 BOOTSTRAP_HASKELL_MINIMAL=1 sh
+ghcup run --ghc 8.10.7 --cabal latest --hls latest --stack latest --install -- code Setup.hs
 ```
 
-This will just install `ghcup` and on windows additionally `msys2`.
+This will execute vscode with GHC set to 8.10.7 and all other tools to their latest version.
 
-For the full list of env variables and parameters to tweak the script behavior, see:
+# Troubleshooting
 
-* [bootstrap-haskell for linux/darwin/freebsd](https://gitlab.haskell.org/haskell/ghcup-hs/-/blob/master/scripts/bootstrap/bootstrap-haskell#L7)
-* [bootstrap-haskell.ps1 for windows](https://gitlab.haskell.org/haskell/ghcup-hs/-/blob/master/scripts/bootstrap/bootstrap-haskell.ps1#L17)
+## Script immediately exits on windows
 
-### Example github workflow
+There are two possible reasons:
 
-On github workflows you can use [https://github.com/haskell/actions/](https://github.com/haskell/actions/)
+1. your company blocks the script (some have a whitelist)... ask your administrator
+2. your Antivirus or Windows Defender interfere with the installation. Disable them temporarily.
 
-If you want to install ghcup manually though, here's an example config:
+## C compiler cannot create executables
 
-```yml
-name: Haskell CI
+### Darwin
 
-on:
-  push:
-    branches: [ master ]
-  pull_request:
-    branches: [ master ]
+You need to update your XCode command line tools, e.g. [like this](https://stackoverflow.com/questions/34617452/how-to-update-xcode-from-command-line).
 
-jobs:
-  build-cabal:
+## Certificate authority errors (curl)
 
-    runs-on: ${{ matrix.os }}
-    strategy:
-      fail-fast: false
-      matrix:
-        os: [ubuntu-latest, macOS-latest, windows-latest]
-        ghc: ['8.10.7', '9.0.1']
-        cabal: ['3.4.0.0']
+If your certificates are outdated or improperly configured, curl may be unable
+to download ghcup.

-    - uses: actions/checkout@v2
+There are two known workarounds:
 
-    - if: matrix.os == 'windows-latest'
-      name: Install ghcup on windows

+1. Tell curl to ignore certificate errors (dangerous): `curl -k https://raw.githubusercontent.com/haskell/ghcup-hs/master/scripts/bootstrap/bootstrap-haskell | GHCUP_CURL_OPTS="-k" sh`
+2. Try to use wget instead: `wget -O /dev/stdout https://raw.githubusercontent.com/haskell/ghcup-hs/master/scripts/bootstrap/bootstrap-haskell | BOOTSTRAP_HASKELL_DOWNLOADER=wget sh`
 
-    - if: matrix.os == 'windows-latest'

-## Tips and tricks
-
-### with_ghc wrapper (e.g. for HLS)
-
-Due to some HLS [bugs](https://github.com/mpickering/hie-bios/issues/194) it's necessary that the `ghc` in PATH
-is the one defined in `cabal.project`. With some simple shell functions, we can start our editor with the appropriate
-path prepended.
-
-For bash, in e.g. `~/.bashrc` define:
-
-```sh
-with_ghc() {
-  local np=$(ghcup --offline whereis -d ghc $1 || { ghcup --cache install ghc $1 && ghcup whereis -d ghc $1 ;})
-  if [ -e "${np}" ] ; then
-    shift
-    PATH="$np:$PATH" "$@"
-  else
-    >&2 echo "Cannot find or install GHC version $1"
-    return 1
-  fi
-}
-```
-
-For fish shell, in e.g. `~/.config/fish/config.fish` define:
-
-```fish
-function with_ghc
-  set --local np (ghcup --offline whereis -d ghc $argv[1] ; or begin ghcup --cache install ghc $argv[1] ; and ghcup whereis -d ghc $argv[1] ; end)
-  if test -e "$np"
-    PATH="$np:$PATH" $argv[2..-1]
-  else
-    echo "Cannot find or install GHC version $argv[1]" 1>&2
-    return 1
-  end
-end
-```
-
-Then start a new shell and issue:
-
-```sh
-# replace 'code' with your editor
-with_ghc 8.10.5 code path/to/haskell/source
-```
-
-Cabal and HLS will now see `8.10.5` as the primary GHC, without the need to
-run `ghcup set` all the time when switching between projects.

+GHCup has two main channels for every tool: **recommended** and **latest**. By default, it installs *recommended*.
+
+*latest* follows the latest release of every tool, while *recommended* is at the discretion of the GHCup maintainers and based on community adoption (hackage libraries, tools like HLS, stackage support, etc.) and known bugs.
+
+Also see [tags and shortcuts](../guide/#tags-and-shortcuts) for more information.
+

+
+
+### Linux (generic)
+
+#### Generic
+
+You need the following packages: curl g++ gcc gmp make ncurses realpath xz-utils. Consult your distro documentation on the exact names of those packages.
+
+### Darwin
+
+#### Generic
+
+On OS X, in the course of running ghcup you will be given a dialog box to install the command line tools. Accept and the requirements will be installed for you. You will then need to run the command again.
+On Darwin M1 you might also need a working llvm installed (e.g. via brew) and have the toolchain exposed in PATH.
+
+### FreeBSD
+
+#### Generic
+
+The following distro packages are required: `curl gcc gmp gmake ncurses perl5 libffi libiconv`
+
+
+### Windows
+
+#### Generic
+
+On Windows, msys2 should already have been set up during the installation, so most users should just proceed. If you are installing manually, make sure to have a working mingw64 toolchain and shell.
+
+## Next steps
+
+1. Follow the [First steps guide](../steps) on how to build a "Hello world" program, use `ghc`, run an interactive REPL and create a Haskell project
+2. To understand the difference and overlap of `stack` and `cabal`, read on [here](https://gist.github.com/merijn/8152d561fb8b011f9313c48d876ceb07)
+3. To learn Haskell proper check out the links at [How to learn Haskell proper](../steps#how-to-learn-haskell-proper)
+4. To learn more about Haskell Toolchain management, check out the [ghcup user guide](./guide.md)
+
+## Uninstallation
+
+On linux, just run `ghcup nuke`, then make sure any ghcup added lines in your `~/.bashrc` (or similar) are removed.
+
+On windows, right click on the `Uninstall Haskell.ps1` PowerShell script on your Desktop and select *Run with PowerShell*.

 ```
 
+### Windows
+
+1. Install ghcup binary
+    - choose a base directory for installation, e.g. `C:\` that has sufficient space
+    - then create the directory, e.g. `C:\ghcup\bin`
+    - download the binary: https://downloads.haskell.org/~ghcup/x86_64-mingw64-ghcup.exe
+    - place it as `ghcup.exe` into e.g. `C:\ghcup\bin`
+2. Install MSYS2
+    - download https://repo.msys2.org/distrib/msys2-x86_64-latest.exe and execute it
+    - remember the installation destination you choose (default is `C:\msys64`)
+    - finish the installation
+* Add environment variables and update `Path`
+    - open search bar and type in "Edit the system environment variables", then open it
+    - click on "Environment Variables..." at the near bottom
+    - in the upper half, select `Path` variable and double click on it
+    - in the new window, click "New", type in `C:\ghcup\bin` (depending on step 1.) and press enter
+    - click "OK" at the bottom
+    - in the upper half, click on "New..."
+    - enter `GHCUP_MSYS2` under "Variable name" and the installation destination from step 2. under "Variable value"
+    - click "OK" at the bottom
+    - in the upper half, click on "New..."
+    - enter `GHCUP_INSTALL_BASE_PREFIX` under "Variable name" and based on the installation destination from step 1. enter the device directory (default `C:\`)
+    - click "OK" at the bottom
+    - in the upper half, click on "New..."
+    - enter `CABAL_DIR` under "Variable name" and based on the installation destination from step 1. enter the device directory + `cabal` subdir (default `C:\cabal`)
+    - click "OK" at the bottom
+    - click "OK" at the bottom
+    - click "OK" at the bottom
+3. Install tools
+    - open powershell
+    - run `ghcup install ghc --set recommended`
+    - run `ghcup install cabal latest`
+    - run `ghcup install stack latest`
+    - run `ghcup install hls latest`
+    - run `cabal update`
+4. Update msys2
+    - run `ghcup run -m -- pacman --noconfirm -Syuu`
+    - run `ghcup run -m -- pacman --noconfirm -Syuu`
+    - run `ghcup run -m -- pacman --noconfirm -S --needed curl autoconf mingw-w64-x86_64-pkgconf`
+    - run `ghcup run -m -- pacman --noconfirm -S ca-certificates`
+5. Update cabal config
+    - go to e.g. `C:\cabal` (based on device you picked in 1.)
+    - open file `config`
+    - uncomment `extra-include-dirs` (the `-- `) and add the value (depending on installation destination you chose in 2.), e.g. `C:\msys64\mingw64\include`... so the final line should be `extra-include-dirs: C:\msys64\mingw64\include`
+    - uncomment `extra-lib-dirs` and do the same, adding `C:\msys64\mingw64\lib`
+    - uncomment `extra-prog-path` and set it to `C:\ghcup\bin, C:\cabal\bin, C:\msys64\mingw64\bin, C:\msys64\usr\bin`, depending on your install destinations from 1. and 2.
+6. Set up msys2 shell
+    - run `ghcup run -m -- sed -i -e 's/db_home:.*$/db_home: windows/' /etc/nsswitch.conf` to make the HOME in your msys2 shell match the one from windows
+    - make a desktop shortcut from `C:\msys64\msys2_shell.cmd`, which will allow you to start a proper msys2 shell
+    - run `ghcup run -m -- sed -i -e 's/#MSYS2_PATH_TYPE=.*/MSYS2_PATH_TYPE=inherit/' /c/msys64/msys2.ini`
+    - run `ghcup run -m -- sed -i -e 's/rem set MSYS2_PATH_TYPE=inherit/set MSYS2_PATH_TYPE=inherit/' /c/msys64/msys2_shell.cmd`
+
+All set. You can run `cabal init` now in an empty directory to start a project.
+
+## Esoteric distros
+
+### Void Linux
+
+Since void linux can be installed with glibc and musl, it's hard to support correctly with ghcup.
+One way to make ghcup work on **Void Linux musl** is to follow the [Overriding distro detection](../guide/#overriding-distro-detection)
+section and tell it to consider Alpine bindists only. E.g.:
+
+```sh
+curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | BOOTSTRAP_HASKELL_MINIMAL=1 sh
+source ~/.ghcup/env
+ghcup config set platform-override '{ "arch": "A_64", "platform": { "contents": "Alpine", "tag": "Linux" }, "version": "3.17" }'
+ghcup install cabal --set latest
+ghcup install ghc --set latest
+ghcup install stack --set latest
+ghcup install hls --set latest
+```
+
 ## Vim integration
 
 See [ghcup.vim](https://github.com/hasufell/ghcup.vim).
 
+## VSCode integration
+The developers of the Haskell Language Server offer an [extension](https://github.com/haskell/vscode-haskell) tightly integrated with the [Haskell Language Server](https://github.com/haskell/haskell-language-server). To get started:
+
+1. Install GHCup. During installation, opt in to install the Haskell Language Server (HLS).
+2. Install the extension (from VSCode: Ctrl + P and then `ext install haskell.haskell`).
+3. Make sure your project uses the GHC version installed from GHCup (otherwise HLS is likely to fail on launch):
+    - instructions for [stack](https://docs.haskellstack.org/en/stable/yaml_configuration/#system-ghc)
+
+On Linux, some users have reported an issue when VSCode is not launched from a terminal ("cannot find ghc version"). A solution is to [let HLS know about your GHCup on $PATH](https://github.com/haskell/vscode-haskell#stackcabalghc-can-not-be-found).

+# First steps
+
+In this guide we'll take a look at a few core tools that are installed
+with the Haskell toolchain, namely, `ghc`, `runghc` and `ghci`.
+These tools can be used to compile, interpret or explore Haskell programs.
+
+First, let's start by opening your system's command line interface
+and running `ghc --version` to make sure we have successfully
+installed a Haskell toolchain:
+
+```
+➜ ghc --version
+The Glorious Glasgow Haskell Compilation System, version 8.10.7
+```
+
+If this fails, consult [the Getting started page](../install) for information on
+how to install Haskell on your computer.
+
+This guide is partly based on [Gil Mizrahi's blog](https://gilmi.me/blog/post/2021/08/14/hs-core-tools).
+
+## Compiling programs with ghc
+
+Running `ghc` invokes the Glasgow Haskell Compiler (GHC), and can be used to
+compile Haskell modules and programs into native executables and libraries.
+
+Create a new Haskell source file named `hello.hs`,
+and write the following code in it:
+
+```hs
+main = putStrLn "Hello, Haskell!"
+```
+
+Now, we can compile the program by invoking `ghc` with the file name:
+
+```sh
+➜ ghc hello.hs
+[1 of 1] Compiling Main             ( hello.hs, hello.o )
+Linking hello ...
+```
+
+For more in-depth information about the files `ghc` produces,
+follow the [GHC user guide](https://downloads.haskell.org/ghc/latest/docs/html/users_guide/using.html#getting-started-compiling-programs) guide.
+
+Now we run our program:
+
+```sh
+➜ ./hello 
+Hello, Haskell!
+```
+
+Alternatively, we can skip the compilation phase by using the command `runghc`:
+
+```sh
+➜ runghc hello.hs
+Hello, Haskell!
+```
+
+`runghc` interprets the source file instead of compiling it and does not
+create build artifacts. This makes it very useful when developing programs
+and can help accelerate the feedback loop. More information about `runghc`
+can be found in the
+[GHC user guide](https://downloads.haskell.org/ghc/latest/docs/html/users_guide/runghc.html).
+
+### Turning on warnings
+
+The `-Wall` flag will enable GHC to emit warnings about our code.
+
+```sh
+➜ ghc -Wall hello.hs -fforce-recomp
+[1 of 1] Compiling Main             ( hello.hs, hello.o )
+
+hello.hs:1:1: warning: [-Wmissing-signatures]
+    Top-level binding with no type signature: main :: IO ()
+  |
+1 | main = putStrLn "Hello, Haskell!"
+  | ^^^^
+Linking hello ...
+```
+
+While Haskell can infer
+the types of most expressions, it is recommended that top-level definitions
+are annotated with their types.
+
+Now our `hello.hs` source file should looks like this:
+
+```hs
+main :: IO ()
+main = putStrLn "Hello, world!"
+```
+
+And now GHC will compile `hello.hs` without warnings.
+
+## An interactive environment
+
+GHC provides an interactive environment in a form of a
+Read-Evaluate-Print Loop (REPL) called GHCi.
+To enter the environment run the program `ghci`.
+
+```sh
+➜ ghci
+GHCi, version 9.0.2: https://www.haskell.org/ghc/  :? for help
+ghci> 
+```
+
+It provides an interactive prompt where Haskell expressions can be written and
+evaluated.
+
+For example:
+
+```sh
+ghci> 1 + 1
+2
+ghci> putStrLn "Hello, world!"
+Hello, world!
+```
+
+We can define new names:
+
+```sh
+ghci> double x = x + x
+ghci> double 2
+4
+```
+
+We can write multi-line code by surrounding it with `:{` and `:}`:
+
+```hs
+ghci> :{
+| map f list =
+|     case list of
+|         [] -> []
+|         x : xs -> f x : map f xs
+| :}
+ghci> map (+1) [1, 2, 3]
+[2,3,4]
+
+```
+
+We can import Haskell source files using the `:load` command (`:l` for short):
+
+```sh
+ghci> :load hello.hs
+[1 of 1] Compiling Main             ( hello.hs, interpreted )
+Ok, one module loaded.
+ghci> main
+Hello, Haskell!
+```
+
+As well as import library modules:
+
+```sh
+ghci> import Data.Bits
+ghci> shiftL 32 1
+64
+ghci> clearBit 33 0
+32
+```
+
+We can even ask what the type of an expression is using the `:type` command
+(`:t` for short):
+
+```sh
+λ> :type putStrLn
+putStrLn :: String -> IO ()
+```
+
+To exit `ghci`, use the `:quit` command (or `:q` for short)
+
+```sh
+ghci> :quit
+Leaving GHCi.
+```
+
+A more thorough introduction to GHCi can be found in the
+[GHC user guide](https://downloads.haskell.org/~ghc/latest/docs/html/users_guide/ghci.html).
+
+### Using external packages in ghci
+
+By default, GHCi can only load and use packages that are
+[included with the GHC installation](https://downloads.haskell.org/ghc/9.4.2/docs/users_guide/9.4.2-notes.html#included-libraries).
+
+However, users of the [cabal-install](https://www.haskell.org/cabal) and
+[stack](http://haskellstack.org) build tools can download and load external packages
+very easily using the following commands:
+
+cabal-install:
+
+```sh
+cabal repl --build-depends async,say
+```
+
+Stack:
+
+```sh
+stack exec --package async --package say -- ghci
+```
+
+And the modules of the relevant packages will be available for import:
+
+```sh
+GHCi, version 9.0.1: https://www.haskell.org/ghc/  :? for help
+ghci> import Control.Concurrent.Async 
+ghci> import Say
+ghci> concurrently_ (sayString "Hello") (sayString "World")
+Hello
+World
+```
+
+Stack users can also use this feature with `runghc` and `ghc` by replacing
+`ghci` in the command above, and cabal-install users can generate an
+environment file that will make `async` and `say` visible for GHC tools
+in the current directory using this command:
+
+```sh
+cabal install --lib async say --package-env .
+```
+
+Many more packages are waiting for you on [Hackage](https://hackage.haskell.org).
+
+## Creating a proper package with modules
+
+The previous methods to compile Haskell code are for quick experiments and small
+programs. Usually in Haskell, we create cabal projects, where build tools such as
+`cabal-install` or `stack` will install necessary dependencies and compile modules
+in correct order. For simplicity's sake, this section will only use `cabal-install`.
+
+To get started, run:
+
+```sh
+mkdir haskell-project
+cd haskell-project
+cabal init --interactive
+```
+
+If you let it generate a simple project with sensible defaults, then you should have these files:
+
+* `src/MyLib.hs`: the library module of your project
+* `app/Main.hs`: the entry point of your project
+* `haskell-project.cabal`: the "cabal" file, describing your project, its dependencies and how it's built
+
+To build the project, run:
+
+```sh
+cabal build
+```
+
+To run the main executable, run:
+
+```sh
+➜ cabal run
+Hello, Haskell!
+someFunc
+```
+
+### Adding dependencies
+
+Now let's add a dependency and adjust our library module. Open `haskell-project.cabal`
+and find the library section:
+
+```
+library
+    exposed-modules:  MyLib
+
+    -- Modules included in this library but not exported.
+    -- other-modules:
+
+    -- LANGUAGE extensions used by modules in this package.
+    -- other-extensions:
+    build-depends:    base ^>=4.14.3.0
+    hs-source-dirs:   src
+    default-language: Haskell2010
+```
+
+The interesting parts here are `exposed-modules` and `build-depends`.
+To add a dependency, it should look like this:
+
+```
+    build-depends:    base ^>=4.14.3.0
+	                , directory
+```
+
+Now open `src/MyLib.hs` and change it to:
+
+```hs
+module MyLib (someFunc) where
+
+import System.Directory
+
+someFunc :: IO ()
+someFunc = do
+  contents <- listDirectory "src"
+  putStrLn (show contents)
+```
+
+### Adding modules
+
+To add a module to your package, adjust `exposed-modules`, like so
+
+```
+    exposed-modules:  MyLib
+	                  OtherLib
+```
+
+then create `src/OtherLib.hs` with the following contents:
+
+```hs
+module OtherLib where
+
+otherFunc :: String -> Int
+otherFunc str = length str
+```
+
+To use this function interactively, we can run:
+
+```sh
+➜ cabal repl
+ghci> import OtherLib
+ghci> otherFunc "Hello Haskell"
+13
+```
