 # GHCup metadata
 
-## Adding a new GHC version
+## For end users
+
+### Metadata variants (distribution channels)
+
+* `ghcup-A.B.C.yaml`: this is the main metadata and what ghcup uses by default
+* `ghcup-vanilla-A.B.C.yaml`: this is similar to `ghcup-A.B.C.yaml`, but only uses upstream bindists (no patches/fixes are applied, no missing platforms added)
+* `ghcup-prereleases-A.B.C.yaml`: this contains pre-releases of all tools
+* `ghcup-cross-A.B.C.yaml`: this contains (usually experimental) cross compilers
+
+### Using the metadata
+
+If you want access to both pre-releases and cross compilers, run:
+
+```
+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
+```
+
+## For contributors
+
+### Adding a new GHC version
 
 1. open the latest `ghcup-<yaml-ver>.yaml`
 2. find the latest ghc version (in yaml tree e.g. `ghcupDownloads -> GHC -> 8.10.7`)
@@ -11,3 +31,24 @@
 7. run `cabal run ghcup-gen -- check-tarballs    -f ghcup-<yaml-ver>.yaml -u 'ghc-8\.10\.8'`
 8. run `cabal run ghcup-gen -- generate-hls-ghcs -f ghcup-<yaml-ver>.yaml --format json -o hls-metadata-0.0.1.json`
 9. run `cabal run ghcup-gen -- generate-table    -f ghcup-<yaml-ver>.yaml --stdout` and adjust [docs/install](https://gitlab.haskell.org/haskell/ghcup-hs/-/blob/master/docs/install.md) tables
+
+### During a pull request
+
+* make sure to always add new versions to both `ghcup-A.B.C.yaml` and `ghcup-vanilla-A.B.C.yaml`
+* make sure to run the bindist action to check tool installation on all platforms: https://github.com/haskell/ghcup-metadata/actions/workflows/bindists.yaml
+  - this is a manual pipeline
+  - set the appropriate parameters
+* make sure to sign the yaml files you edited, e.g.: `gpg --detach-sign -u <your-email> ghcup-0.0.7.yaml` or ask a GHCup developer to sign
+  - PGP pubkeys need to be cross-signed by the GHCup team
+  - they need to be added to the CI: https://github.com/haskell/ghcup-metadata/blob/develop/.github/workflows/sigs
+  - and need to be documented on the homepage
+    * https://github.com/haskell/ghcup-hs/blob/master/docs/guide.md#gpg-verification
+	* https://github.com/haskell/ghcup-hs/blob/master/docs/install.md#unix
+
+### Understanding tags
+
+Tags are documented [here](https://github.com/haskell/ghcup-hs/blob/master/lib/GHCup/Types.hs). Search for `data Tag`.
+Some tags are unique. Uniqueness is checked by `cabal run ghcup-gen -- check -f ghcup-<yaml-ver>.yaml`.
+
+If you want to check prereleases, do: `cabal run ghcup-gen -- check -f ghcup-prereleases-<yaml-ver>.yaml --channel=prerelease`
