+
+* https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/140
+* https://gitlab.haskell.org/haskell/ghcup-hs/-/issues/197
+
+#### WSL1
+
+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.
+
+#### Linux ARMv7/AARCH64
+
+Lower availability of bindists. HLS only has experimental ones. Stack now supported currently.

+### 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

+### 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`.

-3. Add ChangeLog entry
-
-4. Add/fix downloads in `ghcup-<ver>.yaml`, then verify with `ghcup-gen check -f ghcup-<ver>.yaml`

-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`
-
-7. Add release artifacts to yaml file (see point 4.)

+# 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`
