 ## Updating the Homebrew Formula
 
-([`zrok.rb`](https://github.com/Homebrew/homebrew-core/blob/master/Formula/z/zrok.rb)) is a Ruby script in `Homebrew/homebrew-core` that defines the build procedure for the `zrok` binary. The Homebrew workflow triggered by the "released" event in GitHub sends a pull request to update the zrok formula. Usually, the only differences are the HTTP URL of the release's source code archive and it's checksum. It's also necessary to send a PR for the Ruby script when the zrok build procedure changes  ([example PR](https://github.com/Homebrew/homebrew-core/pull/210917)).

+Finally, if correcting a failed GitHub Actions check on a PR based on Homebrew/homebrew-core master branch, then push commits as the ziti-ci user with the "gh_ci_key" SSH key to update the PR. A valid commit message is just the formula name and new version string, e.g., "zrok 1.0.0".
