 Cabal does not follow SemVer and Stack has both SemVer compatible version numbers as well as PVP-style versions; due to this, support for "resolving" a version like `X.X` into the latest `X.X.Y` or `X.X.Y.Y` version is tricky.
 To avoid complications, all recognized versions of GHC, Cabal, and Stack are in `src/versions.json`; these versions are supported across all three operating systems.
 When a new release of GHC, Cabal, or Stack comes out, the `src/versions.json` file will need to be updated accordingly.
+
+### Adding new versions
+
+- Add new versions to `src/versions.json` and `README.md`.
+- Take a look at `.github/workflows/workflow.yml`.
+  The new versions should be covered by the `latest` jobs there, however they can bump the next-to-latest versions out of CI.
+  Make sure all recent versions are covered by the CI.
