title: Installing firebase with Cocoapods
body: <p>I'm new using cocoapods and I still don't understand it very well. I need to use firebase in my app, but I'm having problems with it. 
  I used this to prepare cocoapods on my mac:</p>
  
  <pre><code>$ sudo gem install cocoapods
  </code></pre>
  
  <p>And then another time to update it:</p>
  
  <pre><code>$ [sudo] gem install cocoapods
  </code></pre>
  
  <p>And i didn't had any problem. Now I want to add the firebase library and I don't know how. I go to firebase in the cocoapods page (<a href="https://cocoapods.org/?q=firebase" rel="noreferrer">here it is</a>) and the only thing it says:
  INSTALLATION:</p>
  
  <pre><code>pod 'Firebase'
  </code></pre>
  
  <p>When I use this on the terminal it says: [!] Unknown command: <code>Firebase</code></p>
  
  <p>What am I doing wrong? Maybe I have to download something, don't know.</p>
  
  <p>Thanks for any help.</p>
