+Great for use as a commit-msg git hook or as part of your gating script in a CI pipeline (e.g. jenkins, github actions).
+Many of the gitlint validations are based on `well-known`_ community_ `standards`_, others are based on checks that
+we've found useful throughout the years. Gitlint has sane defaults, but you can also easily customize it to your
+own liking.
