-## 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
-    - any trust issues relating to missing checksums or GPG signatures is a bug and given high priority

 ## FAQ
 
-### Is ghcup really the main installer?
-
-This is based on the Haskell survey results from 2022, which show that more
-than half of survey participants use GHCup: https://taylor.fausak.me/2022/11/18/haskell-survey-results/

 ### Why reimplement stack?
 
 GHCup is not a reimplementation of stack. The only common part is automatic installation of GHC,

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).

-### 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`.
-
-## 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. `ghcup tui` is only available on non-windows platforms
-2. legacy subcommands `ghcup install` (without a tool identifier) and `ghcup install-cabal` may be removed in the future
-
-# Configuration
+## 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).
 
 Partial configuration is fine. Command line options always override the config file settings.
 
-## Overriding distro detection
-
-If you're running e.g. an Ubuntu derivate based on 18.04 and ghcup is picking bindists that
-don't work well, you could do this in `config.yaml`:
-
-```yml
-platform-override:
-  arch: A_64
-  platform:
-    contents: Ubuntu
-    tag: Linux
-  version: '18.04'
-```
-
-## Env variables
-
-This is the complete list of env variables that change GHCup behavior:
-
-* `GHCUP_USE_XDG_DIRS`: see [XDG support](#xdg-support) above
-* `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
-
-The metadata are the files that 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)
-
-### Mirrors
-
-GHCup allows to use custom mirrors/download-info hosted by yourself or 3rd parties.
-
-To use a mirror, set the following option in `~/.ghcup/config.yaml`:
-
-```yml
-url-source:
-  # Accepts file/http/https scheme
-  OwnSource: "https://some-url/ghcup-0.0.6.yaml"
-```
-
-See [config.yaml](https://github.com/haskell/ghcup-hs/blob/master/data/config.yaml)
-for more options.
-
-Alternatively you can do it via a cli switch:
-
-```sh
-ghcup --url-source=https://some-url/ghcup-0.0.6.yaml list
-```

-### (Pre-)Release channels
-
-A release channel is basically just a metadata file location. You can add additional release
-channels that complement the default one, such as the **prerelease channel** like so:
-
-```sh
-ghcup config add-release-channel https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.7.yaml
-```
-
-This will result in `~/.ghcup/config.yaml` to contain this record:
-
-```yml
-url-source:
-  AddSource:
-  - Right: https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.7.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: []
-```
-
-If you want to combine your release channel with a mirror, you'd do it like so:
-
-```yml
-url-source:
-  OwnSource:
-  # base metadata
-  - "https://mirror.sjtu.edu.cn/ghcup/yaml/ghcup/data/ghcup-0.0.6.yaml"
-  # prerelease channel
-  - "https://raw.githubusercontent.com/haskell/ghcup-metadata/master/ghcup-prereleases-0.0.7.yaml"
-```
-
-### Nightlies
-
-Nightlies are just a nother release channel. Currently, only GHC supports nightlies, which are binary releases
-that are built every night from `master`.
-
-To add the nightly channel, run:
-
-```sh
-ghcup config add-release-channel https://ghc.gitlab.haskell.org/ghcup-metadata/ghcup-nightlies-0.0.7.yaml
-```
-
-To list all nightlies from 2023, run:
-
-```sh
-ghcup list --show-nightly --tool=ghc --since=2023-01-01
-```
-
-Ways to install a nightly:
-
-```sh
-# by date
-ghcup install ghc 2023-06-20
-# by version
-ghcup install ghc 9.7.20230619
-# by tag
-ghcup install ghc latest-nightly
-```
-
-## 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: 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
-```
-
-### Strategy 2: 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`.
-
-### 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)
-
-# 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 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.
-
-## 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 paramaters 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:
-
-```sh
-curl --proto '=https' --tlsv1.2 -sSf https://get-ghcup.haskell.org | BOOTSTRAP_HASKELL_NONINTERACTIVE=1 BOOTSTRAP_HASKELL_MINIMAL=1 sh
-```
-
-This will just install `ghcup` and on Windows additionally MSYS2.
-
-See the installation scripts referred to above for the full list of environment
-variables and, in the case of Windows, parameters to tweak the script behavior.
-
-### github workflows
-
-On github workflows you can use [https://github.com/haskell/actions/](https://github.com/haskell/actions/).
-GHCup itself is also pre-installed on all platforms, but may use non-standard install locations.
-
 ## 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.
 
-First, obtain the gpg keys:

 In `GPGStrict` mode, ghcup will fail if verification fails. In `GPGLax` mode it will just print a warning.
 You can also pass the mode via `ghcup --gpg <strict|lax|none>`.
 
-# Tips and tricks
+## Manpages
 
-## ghcup run
+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.
 
-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.:
+## 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).

+
+## 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

+## 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.

+Let's get started....
 
-## How to install
+## Installation
 
 The following commands will download the `ghcup` binary into `~/.ghcup/bin` (or `C:\ghcup\bin` on windows) and then
 run it to interactively install the [Haskell Toolchain](#supported-tools). These commands should be run as **non-root/non-admin

-There's also a [youtube video](https://www.youtube.com/watch?v=bB4fmQiUYPw) explaining installation on windows.

-If you want to know what these scripts do, check out the [source code at the repository](https://github.com/haskell/ghcup-hs/tree/master/scripts/bootstrap). Advanced users may want to perform a [manual installation](#manual-installation) and GPG verify the binaries.
-
-### Which versions get installed?
-
-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.
-
-## System requirements
-
-### Linux Debian
-
-The following distro packages are required: `build-essential curl libffi-dev libffi6 libgmp-dev libgmp10 libncurses-dev libncurses5 libtinfo5`
-
-### Linux Ubuntu
-
-The following distro packages are required: `build-essential curl libffi-dev libffi6 libgmp-dev libgmp10 libncurses-dev libncurses5 libtinfo5`
-
-### Linux Fedora
-
-The following distro packages are required: `gcc gcc-c++ gmp gmp-devel make ncurses ncurses-compat-libs xz perl`
-
-### Linux Mageia
-
-The following distro packages are required: `curl gcc gcc-c++ gmp libffi-devel libffi7 libgmp-devel libgmp10 make libncurses-devel libncurses5 xz perl`
-
-### Linux CentOS
-
-The following distro packages are required: `gcc gcc-c++ gmp gmp-devel make ncurses ncurses-compat-libs xz perl`
-
-### Linux Alpine
-
-The following distro packages are required: `binutils-gold curl gcc g++ gmp-dev libc-dev libffi-dev make musl-dev ncurses-dev perl tar xz`
-
-### Linux VoidLinux
-
-The following distro packages are required: `gcc gmp curl coreutils xz ncurses make ncurses-libtinfo-libs perl tar`
-
-### Linux (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
-
-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
-
-The following distro packages are required: `curl gcc gmp gmake ncurses perl5 libffi libiconv`
-
-Notice that only FreeBSD 13.x is supported. If the installation fails, complaining about `libncursesw.8.so`, you will need to install FreeBSD 12 compat package first, for example, `pkg install misc/compat12x`.
-
-### Windows
-
-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*.
+Advanced users may want to perform a [manual installation](#manual-install) and GPG verify the binaries.

-### 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.

 ## 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).
