Install Jekyll

on Ubuntu 14.04 I use (the second command will take a while to start),

sudo apt-get install ruby1.9.1-dev
sudo gem install jekyll

Example 1

cd /tmp
jekyll new MyNewSite
# It will create a new folder 'MyNewSite' with about.md, _config.yml, css (folder),  
#    _includes (folder), index.html, _layouts (folder), _posts (folder) and _sass (folder).
cd MyNewSite
jekyll serve --watch
# It'll say the Server Address: http://127.0.0.1:4000/
# We can open a browser to see a template of html page created by '''jekyll new''' command.
