Hey there - there aren't any docs. I'll add it to my to-do list, but for now I'll try explain here what the deal is so I can direct others who ask in the interim. (though, probably just skip to the penultimate paragraph and then decide whether the rest is worth reading).
inline generates the template used by export - it's called automatically by compile, and unless you're testing out exporting, you don't need to run it each time. Sharing doesn't make any use of inline. For most testing, you can just open up editor.html in the src directory (if you have trouble with some stuff not working (I can't remember what bits rely on this, definitely export), you have to set up a local http server -
http://www.linuxjournal.com/content/tech-tip-really-simple-http-server-python has the easiest instructions for this, if you have python. Inline calls this node.js program -
https://github.com/remy/inliner , which you'll have to have installed for it to work.
please please please don't try to convince me that it's not necessary. It's *very* likely not worth the trouble.
If you want to compress the website, which I don't really recommend, tbh, you'll have to call compile
-----
But, so long as you don't want to produce a compressed version of the site, and don't need to test out the export option, you don't need to run any scripts. For running test branches, fixing bugs, implementing new features, it's enough (I'm pretty sure).

Thanks a lot for mentioning this. A couple of people've figured it out by themselves, but it's good to have this info public.
Peace,
