A number of my repos are listed.
But the weird part is that it also lists a repo I don't recognize. The repo does actually exist on my github account, but it's marked as "ignored", and the description says it was automatically exported from Google Code.

Change the stylesheet and you change how the document is rendered. "Reader mode" is just a minimalist stylesheet built into the browser.
