This is how you add a Flattr sponsorship button on Github. It’s really easy!

Add your Github in the profile settings: flattr.com/settings/profile Go to your repositories settings page. (The URL is like this https://github.com/REPONAME/REPONAME/settings) Add your Flattr contribution link in the “Features” section of the repository settings page, it should be formatted as custom:flattr.com/github/GITHUBUSERNAME

This will add a sponsor link pointing to our new one page recurring Flattr contribution signup to your Github repo. Here is a button in action you can try, (mid top of page) https://github.com/da2x/EdgeDeflector

If you want to support some other nice open source projects we would recommend Gimp and GNU as a great start.

We have lots more of this coming, and as always questions goes in the comments.
