title: Adding home-brew to PATH
body: <p>I just installed Home-brew and now I'm trying to insert the home-brew directory at the top of my path environment variable by typing in two commands inside my terminal. My questions are these:</p>
  
  <p>What is a path environment variable?</p>
  
  <p>Are the two codes provided me correct?</p>
  
  <pre><code>echo "export Path=/usr/local/bin:$PATH" &gt;&gt; ~/.bash_profile &amp;&amp; source  ~/.bash_profile
  </code></pre>
  
  <p>After this I am to type in brew doctor. Nothing is happening as far as I can see.
  Can anyone offer me some advice or direction?</p>
