Ask HN: Simple Git doc mirror/hosting?

I've finally started properly documenting Heresy, but my hosting method at this point is tedious. I write the docs in LyX and output to HTML and push this to master, but to actually host it in a linkable way I have to then manual copy it over to the gh-pages branch so that I can actually then share it publicly. I swear it used to be the case that I could simply keep the two branches in sync with a pull request, but they seem to have changed the way the gh-pages branch works so that's no longer an option. Ideally it'd be nice to just have a site somewhere that keeps in sync automatically the HTML file and hosts it so I don't have to constantly mess with it. I found a site here: http://git-doc.com/ It seems to have the functionality I want, but the list of permissions it demands is ludicrous, more or less requiring full access to my entire GH account. Anyone know any alternatives?
