title: Error: src refspec master does not match any. when trying to push to Bitbucket repo
body: <p>I created a new repo on <code>Bitbucket</code> and followed the very simple steps prescribed. First I did <code>git init</code> in my local folder to be version controlled. Then I did:</p>
  
  <pre><code>git remote add origin https://my_account@bitbucket.org/my_account/my_project.git
  </code></pre>
  
  <p>That worked. The last step was:</p>
  
  <pre><code>git push -u origin master
  </code></pre>
  
  <p>I obtained the following:</p>
  
  <pre><code>error: src refspec master does not match any.
  error: failed to push some refs to 'https://my_account@bitbucket.org/my_account/my_project.git'
  </code></pre>
  
  <p>Why do I get this error?</p>
