How to run the documentation locally?

Created by: danse

It seems to be obvious, but yet i am not able too see my changes locally. Maybe this issue may lead to a small improvement in the getting started section.

I am working on the current master, 97a3f94075e84e8b085ae0d5e9e52b250ff029d9. What i did is installing the Node dependencies, Jekyll and Ruby, then running:

$ grunt dist
$ grunt jekyll
$ jekyll serve

All commands seem to be successful, but navigating to the served site, i do not see my changes. I also tried jekyll build, it also seems to be successful, but no changes on the served doc. I see that my dist/css/bootstrap.css is different from _gh_pages/dist/css/bootstrap.css, but i would not know how to align them, besides manually copy the files
