syncthing-android/wiki/Sync-N-first-files-get-N-movies-for-watching.md

User [SerVB](https://github.com/SerVB) made a script to care about moving files into the Syncthing folder until N movie episodes are present.

See [syncthing#1279](https://github.com/syncthing/syncthing-android/issues/1279) for more details on the idea.

Thanks for your contribution!
