My first memory of browsing a GitHub repository, just a little before I started using Git (and any version control whatsoever), is one of a repository that had a brief description of each file in it right in front of it. Actually, the brief description was the commit message of the last commit that modified each file, you know what I'm talking about, but somehow in that particular repository they did some trick to make these commit messages appear as descriptions of each file. Or maybe it is just an erroneous impression I had at that time.
