see this [issue](https://github.com/mojombo/jekyll/pull/1487) in jekyll repo.
jekyll's docs on windows it's outdated, unclear and not working.(pygments 0.5.2 not working correctly [need 0.5.0], need python version 2.X. jekylll and python 3 not working)
the portable version is good, but I need set the path every time compile css/js and docs.
if best solution is create one TODO in bootstrap repo for instructions of jekyll,I can create the instructions.
Link was the best and detailed documentation I found (and working).
I tested almost all the solutions found. to be totally clear the installation of jekyll
