Igordcsouza/commandsnames

A simple merge, just adding names to commands. Some companies have many commands, and without a name people would have to read all the commands until you find the need for the project. With the names, is simpler to make a 'tutorial' with the order of commands.
Even I also changed the version of ruby, changing from 2.1.2 to the most current version 2.1.3!
Changes made to the layout station below.

Can you add some css around this to vertically center align this?
