+# Guide to contributing to Ocplib-simplex
+
+## Release Process
+
+- Make a PR on `master` to initiate the release. The PR must introduce
+  a new section in `CHANGES.md` with the new version number;
+- Once the PR is merged, create a new `vX.Y.Z` branch for the release from the
+  current `master`.
+
+## Make the release
+
+The release is made using `dune-release`, and follows standard procedure for
+the tool:
+- `dune-release check` performs basic check;
+- `dune-release tag vX.Y.Z` creates a tag on the current branch;
+- `dune-release distrib` creates the distribution archive;
+- `dune-release publish` publishes the release on GitHub;
+- `dune-release opam pkg` creates an archive for opam;
+- `dune-release opam submit` opens a PR on the opam repository.
