title: error using composer to install cakePHP 3
body: <p>i am lost...</p>
  
  <p>i am trying to do it the right way and am following <a href="http://book.cakephp.org/3.0/en/quickstart.html#getting-cakephp" rel="nofollow">the Quick Start Guide for installing cakePHP 3</a> on my ubuntu machine.</p>
  
  <p>Got composer installed. Directory is /var/www/cakephp</p>
  
  <p>and am trying to issue:</p>
  
  <pre><code>php composer.phar create-project --prefer-dist cakephp/app mayapp
  </code></pre>
  
  <p>or</p>
  
  <pre><code>composer create-project --prefer-dist cakephp/app may app
  </code></pre>
  
  <p>then i am simply getting:</p>
  
  <pre><code>[InvalidArgumentException]                              
    Could not find package cakephp/app with stability stable.
  </code></pre>
  
  <p>i do not have a clue what i am doing wrong. Any suggestions?</p>
