Another 15 minutes fiddling with google so:

Sites:

http://wrye-bash.github.io/docs/Wrye%20Bash%20General%20Readme.html
http://msysgit.github.io/
http://utumno.github.io/blog/2013/12/21/set-up-octopress-in-windows-7/

Code:

https://github.com/wrye-bash/wrye-bash.github.io/blob/master/docs/Wrye%20Bash%20General%20Readme.html
https://github.com/msysgit/msysgit.github.com/blob/master/index.html # com
https://github.com/Utumno/Utumno.github.io/blob/master/blog/2013/12/21/set-up-octopress-in-windows-7/index.html

Notice that https://wrye-bash.github.io/ gives a 404 - there should be an https://github.com/wrye-bash/wrye-bash.github.io/blob/master/index.html apparently.

Ah, yes - How do I clone a github wiki?:

Append .wiki.git to the repo name, i.e. if your repo name was foobar git clone git@github.com:myusername/foobar.git would be the path to clone your repo and git clone git@github.com:myusername/foobar.wiki.git would be the path to clone its wiki.

I ’m sure this post will grow.
