+Contributing to eredis
+======================
+
+Requirements: Erlang/OTP, rebar3 and make. For tests, also Docker and OpenSSL.
+
+* `make test` runs the tests using Docker and generates TLS certificates using
+  OpenSSL. If you can't run it or if some test (e.g. the IPv6 test) fails, it's
+  fine as long as it passes in the automated builds.
+* When docs are affected, run `make edoc` and commit the changed Markdown files
+  under `doc/`.
+* Don't update the version unless agreed with the maintainers.
+
+Releasing a new version
+-----------------------
+
+Normally done by the maintainers.
+
+* Update the version in `src/eredis.app.src` and `mix.exs`.
+* Update CHANGELOG.md and add what's new since the last version. (Use e.g. `git
+  log *PREV_VERSION*..HEAD`).
+* Check that documentation is generated and commited using `make edoc`.
+* Commit the changes, push and check the build.
+* Publish to Hex using `make publish` (requires `mix` and a Hex account with
+  rights to publish this project). (This can be done later.)
+* Create an annotated tag on the form vMAJOR.MINOR.PATCH, `git tag -a v0.0.0`.
+  Write a very short message with the most important changes (one line or a few
+  bullets).
+* Push the tag using `git push --tags`.
