Just go ahead and edit files through GitHub. The HTML will be generated using GH Jekyll support and displayed (it takes seconds to reload).
If you wish to run Jekyll locally just install the Ruby Gem gem install jekyll
Note: If you're a purist start with RVM, then install Ruby, create a gemset and install jekyll.
Next, run jekyll build --watch in source directory and visit page in just generated _site dir.
Due to --watch option in Jekyll the source will be rebuilt on change.
