+## RLS - Editor/IDE Issues
+
+For some reason (as of this writing) RLS has issues with multiple versions of `ffmpeg-dev` downloaded (under `target`). If there’s something I can fix on my side I’m happy to implement such changes. For now I’m just resorting my deleting the cache folder whenever I update `ffmpeg-dev`.
