+## Common Tasks
+
+### 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 -> 8.10.3`)
+3. copy-paste it
+4. adjust the version, tags, changelog, source url
+5. adjust the various bindist urls (make sure to also change the yaml anchors)
+6. run `cabal run exe:ghcup-gen -- check-tarballs -f ghcup-<yaml-ver>.yaml -u 'ghc-8\.10\.4'`
