+
+Unsupported. GHC may or may not work. Upgrade to WSL2.
+
+#### MacOS <13
+
+Not supported. Would require separate binaries, since >=13 binaries are incompatible.
+Please upgrade.
+
+#### MacOS aarch64
+
+HLS bindists are still experimental. Stack is theoretically supported, but has no binaries yet.
+
+#### FreeBSD
+
+Lacks some upstream bindists and may need compat libs, since most bindists are built on FreeBSD-12.

 Partial configuration is fine. Command line options always override the config file settings.
 
+### 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 key:
+
+```sh
+gpg --batch --keyserver keys.openpgp.org --recv-keys 7784930957807690A66EBDBE3786C5262ECB4A3F
+```
+
+Then verify the gpg key in one of these ways:
+
+1. find out where I live and visit me to do offline key signing
+2. figure out my mobile phone number and call me to verify the fingerprint
+3. more boring: contact me on Libera IRC (`maerwald`) and verify the fingerprint
+
+Once you've verified the key, you have to figure out if you trust me.
+
+If you trust me, then you can configure gpg in `~/.ghcup/config.yaml`:
+
+```yml
+gpg-setting: GPGLax # GPGStrict | GPGLax | GPGNone
+```
+
+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>`.
+
 ### 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.

 ### Shell-completion

+Shell completions are in [scripts/shell-completions](./scripts/shell-completions) directory of this repository.
 
 For bash: install `shell-completions/bash`

 and make sure your bashrc sources the startup script
 (`/usr/share/bash-completion/bash_completion` on some distros).
 
-### Cross support
+### 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](./data/build_mk), copy them somewhere, adjust them and
+pass `--config path/to/build.mk` to `ghcup compile ghc`.

 GHCup always needs to know which version the bindist corresponds to (this is not automatically

+### 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` 
+   ---  
+
+### CI
+
+On windows, ghcup can be installed automatically on a CI runner 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:
+
+```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`.

+# RELEASING
+
+1. Update version in `ghcup.cabal` and `boostrap-haskell` (`ghver` variable at the top of the script)
+
+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
+
+4. Add/fix downloads in `ghcup-<ver>.yaml` (under `data/metadata`), then verify with `ghcup-gen check -f ghcup-<ver>.yaml` and possibly (example only) `ghcup-gen check-tarballs -f ghcup-<ver>.yaml -u 'ghc-8.10.7'`. 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).
+
+5. Commit and git push with tag. Wait for tests to succeed and release artifacts to build.
+
+6. Download release artifacts and upload them `downloads.haskell.org/ghcup` along with checksum files (`sha256sum --tag * > SHA256SUMS && gpg --detach-sign -u <your-email> SHA256SUMS`)
+
+7. Add ghcup release artifacts to ALL yaml files (see point 4.)
+
+8. Upload the final `ghcup-<ver>.yaml` to `webhost.haskell.org/ghcup/data/`.
+
+9. Update `bootstrap-haskell` and `bootstrap-haskell.ps1` to `webhost.haskell.org/ghcup/sh/`
+
+10. Update the ghcup symlinks at `downloads.haskell.org/ghcup`
