 # Automatically update Grub
 #  If you would like Grub to automatically update when a snapshots is made or deleted:
-# - Mount your subvolume which contains snapshots to /.snapshots
-# - Use systemctl start/enable grub-btrfs.path
-#  grub-btrfs.path will automatically (re)generate grub.cfg when a modification appear in /.snapshots
+#  - Use systemctl start/enable grub-btrfs.path
+#  - grub-btrfs.path automatically (re)generates grub.cfg when a modification appears in /.snapshots folder (by default).
+#  - If your snapshots aren't mounted in /.snapshots, you must modify the watch folder using systemctl edit grub-btrfs.path
+#  - See https://github.com/Antynea/grub-btrfs#automatically-update-grub
