The official development of MultiWii is stored in a SVN.
But we are more and more developers who want to use GitHub to code that's why we created the GitHub https://github.com/multiwii organization.
The goal of this organization is to federate and centralize the GitHub community effort behind multiwii.
This project is a mirror of the svn that is syncronized automatically. So you'll see every SVN commit with the commit author and comment.
It contains the gui config part of the MultiWii project.
