title: Push to Heroku denied - "failed to push some refs to 'heroku"
body: <p>I should start by saying I'm totally new to Heroku, and it's all looking pretty to foreign to me right now. </p>
  
  <p>Anyway, I've done the Heroku getting started tutorial, uploading a clone git repo, and this works fine.</p>
  
  <p>I'm now trying to accomplish this with some of my own code, but struggling.</p>
  
  <ol>
  <li>First, I go to my app directory in bash.</li>
  <li>Then I run <code>heroku create</code>. This is successful.</li>
  <li>I then run <code>git push heroku master</code> as instructed in the tutorial, and I receive the following errors: </li>
  </ol>
  
  <p><code>error: src refspec master does not match any.</code></p>
  
  <p><code>error: failed to push some refs to 'heroku'</code></p>
  
  <p>Would appreciate if someone can explain what I am missing here? Thanks in advance.</p>
