 ## Releasing
 
-To release a new version, update the version number in `version.rb`, and then run `bundle exec rake release`, which will create a git tag for the version, push git commits and the created tag, and push the `.gem` file to [rubygems.org](https://rubygems.org).
+To release a new version:
+
+ * Submit a PR with the following changes (see [#30](https://github.com/collectiveidea/protoc-gen-twirp_ruby/pull/30)):
+   * Update the version number in `version.rb`
+   * Update the CHANGELOG.md
+       * Create a section for the new version and move the unreleased version there
+   * Re-generate the example:
+       * `protoc --plugin=protoc-gen-twirp_ruby=./exe/protoc-gen-twirp_ruby --ruby_out=. --twirp_ruby_out=. ./example/hello_world.proto`
+ * Once merged, run the release task from main. Note that we prepend `gem_push=no` to avoid
+   pushing to RubyGems directly; our GitHub publish action will do this for us.
+    *  `gem_push=no bundle exec rake release`
+ * Create a GitHub release: 
+     * `gh release create v<version>`
+     * Edit the release notes to link to the notes in the CHANGELOG.md for the version
