Click on any project in the "Recent Projects" box, or click "All Projects" to find earlier ones.
When you find an interesting one that you know something about, click the "edit" tab and start editing! Don't erase other people's work without discussion; don't assert things you're clueless about; otherwise, there's not much you can do wrong.
It's really that easy to contribute. That's the whole point of this website.
