 A collection of Dockerfiles and a docker-compose configuration to set up a
 seedbox and personal media server.

+Main credits go to [Kelvin Chen](https://github.com/Kelvin-Chen/seedbox) who started the development of its own seedbox using Docker. Mine was first a fork of Kelvin's one, but I made some serious changes in the code and plan to add even more tools and services that keeping this project as a fork started to have less sense as code diverged.
