PHP CS Fixer

[Tom Rushworth]

As a PHP newbee, I thought it would be a good idea to write PHP standard 
code.  To help me do this, I thought I would install CS Fixer because 
Netbeans has a plug in for it. I read that the best way to install CS 
Fixer is with Composer.  I have successfully installed Composer.  But 
now I'm lost. I have no idea how to proceed to install CS Fixer using 
composer. Would someone please share some simple instructions on how to 
proceed?
