+## Updates strategy
+
+Starting from 3.2.1 ([fcab428](https://github.com/an-anime-team/an-anime-game-launcher/commit/fcab428cb40b1457f41e0856f9d1e1473acbe653)) we have 2 branches: stable ([main](https://github.com/an-anime-team/an-anime-game-launcher/tree/main)) and dev ([next](https://github.com/an-anime-team/an-anime-game-launcher/tree/next)). Code changes will be pushed into dev branch and merged into stable once they're ready for new version release
