 * Update the examples in this README if needed.
 
 * Bump the version in `capistrano-twingly.gemspec` in a commit, no need to push (the release task does that).
 
+* Ensure you are signed in to RubyGems.org as [twingly][twingly-rubygems] with `gem signin`.
+
 * Build and [publish](http://guides.rubygems.org/publishing/) the gem. This will create the proper tag in git, push the commit and tag and upload to RubyGems.

-* Update the changelog with [GitHub Changelog Generator](https://github.com/skywinder/github-changelog-generator/) (`gem install github_changelog_generator` if you don't have it, set `CHANGELOG_GITHUB_TOKEN` to a personal access token to avoid rate limiting by GitHub). This command will update `CHANGELOG.md`, commit and push manually.
