I'm unsure if this is the correct place to post this, but if not then someone might be able to move it.

I'm following the Wiki for cross-compiling to a Raspberry Pi: https://wiki.qt.io/RaspberryPi_Beginners_Guide
It contains links to gitorious.org, which seem to have been down now for a month or so and does not seem to come back again.

So someone should update the guide since that Wiki page is probably the goto place for beginners.
