Yup. Totally unofficial. A complete sandbox environment for setting up and maintaining your own port of Sailfish to your own device, a fairly massive guide taking you step-by-step through the process, space on their website to publicize these items, an irc chatroom set up just for porters, and a central hub set up to publish finished ports.

Nope, no official support at all here! This was obviously all done by employees in their free time. We at Jolla put absolutely no effort into this at all, and don't want to help people doing this in any way!
