"Software projects" is very generic. A wannabe-Facebook-clone is a software project, my boring corporate accounting program is a software project, etc. But those aren't your target. Seems like you only want open-source (or at least non-commercial) projects. So say that.

At a guess, you're probably also not targeting teeny-tiny libraries/toolkits, because they don't need much more than Github provides. Only bigger and more mature projects probably have need of this, so you might mention that too.
