+### Config migration remark
+If one of your configs needed migration upon selection. The old config will automagically be backed up to the folder `UserData\HitScoreVisualizer\Backups` (will be created if it doesn't exist) and the migrated config will be saved to the original file instead.
+However, all configs placed in that folder will **NOT** be loaded by HSV. This behavior is by-design and is intended as a safety measure, to prevent accidental migration issues with backups.
+If you want revert to a backup, move one of the files back to the main folder (or another folder in the main folder if you're using a folder structure.)
