+## Release notes
+
+This library uses [semantic versioning](http://semver.org/). For each release, the following needs to be done:
+
+* Update the version number in [version.rb](./lib/ably/version.rb) and commit the change.
+* Run [`github_changelog_generator`](https://github.com/skywinder/Github-Changelog-Generator) to automate the update of the [CHANGELOG](./CHANGELOG.md). Once the `CHANGELOG` update has completed, manually change the `Unreleased` heading and link with the current version number such as `v1.0.0`. Also ensure that the `Full Changelog` link points to the new version tag instead of the `HEAD`. Commit this change.
+* Add a tag and push to origin such as `git tag v1.0.0 && git push origin v1.0.0`
+* Run `rake release` to publish the gem to [Rubygems](http://www.rubydoc.info/gems/ably)
+
