php - Xampp / Composer / Zend Framework 2 Installation issues -

OK, so I have a musician Jason file is a composer. Lock file and a composer file. I think all the information needed to install Z Framework. JSN file is in the file but I do not know what I'm doing with the composer, and do not know how to use the .phar file if someone can help me out, then I'll be great-I am reading a tutorial. And watching the video, but I am quite new to the php technical side. I have never worked with libraries, or prompted the command, so it's all head on the head.

Here's a beginning:

One step : Download composer.phar

  $ curl -sS https://getcomposer.org/installer | Php   
 Step two:  
  $ php composer.phar install   
 This will download all file dependencies mentioned above Composer. In Jason File.  
 A pair notes:  
 
 Above it is assumed that you are using a bass prompt (linux or signin in Windows) if you do not use Linux Download composer.phar from Getcomposer.org  
 You have php in your system path, which means that when you type php in your command line, it will run php executable / binary
