+## Known issues
+When this plugin is enabled, it reacts to all file modifications, whether those are made inside or outside of Obsidian. If you are using a synchronization solution such as Obsidian Sync or [Syncthing](https://www.dsebastien.net/how-i-synchronize-and-backup-my-obsidian-notes/), and if Obsidian is open on multiple devices at the same time, then it can create file conflicts. To avoid this, make sure you don't leave Obsidian open on multiple devices at once, or only enable this plugin on a single device.
