I don't think so. This uses the GitHub API via browser side Javascript to auto generate a page, listing and rendering the READMEs in your recent repos. Plus listing and rendering the .md files in a special "blog-posts" repo.
This is similar to what some big companies do to render a projects page. A copied Twitter's[1][2] a while back when it was simpler[3][4].
There are two use-cases: project pages (from github repo README) and blog-posts (coming from .md files in blog-posts repo). You can choose to not have blog-posts and it will still generate a blog-like site from all your github project READMEs.
