Automatic music sync in highspeed

I used ownCloud before, it was slow as … and then i searched on and found this project! Now i can sync all my music (122GB) on my 16 devices like netbook (ubuntu 16.04), server (ubuntu snappy core on bare metal) etc,

I can take all my files everywhere, Xonotic is also syncd between my computer and friends PC (windewze7Hom€)

Thank you so much and i want to contribute after some study.
