What do you think, @vitiral?

I'm not sure about moving the getting started guide out of the readme, but otherwise I think this is quite a good format that mixes guide and recipe style.

This is really cool! I'm working on getting ergo_fs pushed now, will definitely eventually incorporate this kind of "book style" into ergo.

Glad you like it @vitiral!

I'll try to have some time to get a simple github pages setup going. Ideally, it'll use a custom (but external) theme, so it should be only a matter of adding two or three files to get a nice rendered version of website with these guides.

Alright, Jekyll with custom theme set up! I still need to configure this once it is in master to render, though.

You can find the theme I wrote in https://github.com/killercup/jekyll-theme-rustguides. I haven't spend much time writing CSS for this, but I did make it possible to customize the main color. For quicli, I chose dark blue (at random, basically). The layout is quite barebones right now. It has a list of pages (currently just the one for the commit.md guide), but there is not footer or anything like that.

I think I'll land this tonight, because I won't have much time to work on this for the next week. Feedback (now or later) is very welcome! :)
