 ## Tagging Release Candidates
 
 To tag release candidates
-1. Update the CHANGELOG. Make sure it contains an entry for the version you are
-tagging as well as a dev version things that come after the tag (e.g. a heading
-with the format `<next-version>-dev`).
-2. Run the tests and the linter - `bats test` and `lint.sh`.
-3. Run the release script. The new version must be in the format `0.0.0-rc0`.
-For example: `release/tag.sh 0.0.0-rc0`.
-4. If the release script succeeds, push to GitHub. Make sure to use the correct
-remote to push to the official repository
