I set up Gogs on my Omega2 and found it very valuable to be able to push my small private projects on it. It makes it convenient to share projects between machines and also to back them up!
To set it up I had to cross compile Gogs (written in Go), set up Postgres on the Omega2 and configure Gogs. To set up Postgres, I had to find and install it, set up extra swap space and bring it up.
Since this took me a bit of trial and error, I wrote up the steps I took in case anyone else find them helpful: Setting up Gogs on Omega2
