The GitHub profile feature just went live for a subset of users. Simply creating a repo named after your username, and clicking share to Profile on the sidebar will create a custom profile that shows up just above your pinned projects.
I am still trying to figure out what to put on mine, but this is what I have so far. I feel like mine is a bit big at the moment, I don't like that my pinned repos end up blow the fold.
I tightened mine up and took inspiration from a few others.
