Fork the repo to your account. Edit in the fixes you wanted to do. Commit the changes to the repo. Return to this repo and hit the button that says "Pull Requests". Then while in there hit new pull request. It will ask you what branch of your repo you want it to compare to. Find the branch of the repo you edited in and then go from there.
