gem install bundlerand run next command from root folder:
bundle installTo start Jekyll run:
jekyll serve -wSite will be available at http://127.0.0.1:4000/zeppelin/ or http://localhost:4000/zeppelin/ (on Windows)
NOTE: in this mode all changes to html and data files will be automatically regenerated, but after changing _config.yml you have to restart server.
Note: You need to install Node.js
To watch changes of .sass files and compile it to the .css on a fly change property safe: true to safe: false in _config.yml.
Note: It works only on local machine, because GitHub runs Jekyll in --save mode
