-# Branches
-
-Note that this repository has an **unusual branching strategy**.
-The default branch is the **dev** branch.
-
-The **dev** branch is unreleased, and should work with SPL GameController's master branch.
-When a new game controller release is made (eg. 2023, GermanOpen2023), the package should be backported to active distros (eg. rolling, humble, etc.) and released.
-
-That way, teams don't have to be on the most recent distro to use a package against a recent GameController!
