+# Git Linting
+# It is a tool that checks the semantics of all Git commit messages from the
+# branch-off point off the dev branch up to the latest commit against
+# a set of rules, say you have defined certain formatting within your team.
+# The rules are typically defined in the `.gitlint` file in a repository's
+# root directory.
+# If no `.gitlint` file is present, a default set of rules is applied.

+# This uses Zephyr's own checkpatch script to check against the diff down to the
+# dev branch. Any conflicts must be resolved. It is recommended, to also resolve
+# warnings.

+# Akita Gen 2 Application Pipeline trigger
