How do you successfully use Egit with GitHub?

There seems to be no guide out there that is still valid so I'm asking how to use Egit in Eclipse to push a project to GitHub. I followed some guides but end up with an "Specifications don't match any existing refs in source repository." error in the push dialog.

I'm using Eclipse 3.6.1 and Egit 0.9.1. It should be possible to use Egit shouldn't it? it would be great if you could give a short step by step guide to push a project with Egit successfully.

What is the purpose of EGit?

EGit is an Eclipse Team provider for the Git version control system. Git is a distributed SCM, which means every developer has a full copy of all history of every revision of the code, making queries against the history very fast and versatile.

you should commit the project first onto local repository. and then select Team->Remote->Push... to push the project onto Github.
