[TRaSH-]

You even considered to offer a docker version of subsync ? so you get full platform compatibility ? and easier to integrate with people running a media server

@TRaSH- https://github.com/ethanmlee/subsync/blob/master/Dockerfile It's a start. Anything you think is missing (other than having a prebuilt image available on docker hub or something)
