Android source code submit patch
<p>I want add a patch for android source code.
Have downloaded the code after the instruction from: 
<a href="https://source.android.com/source/downloading.html" rel="nofollow">https://source.android.com/source/downloading.html</a></p>

<p>After that i follow the steps in:
<a href="http://source.android.com/source/submit-patches.html" rel="nofollow">http://source.android.com/source/submit-patches.html</a></p>

<p>When i should start a new repo branch:
repo start NAME .</p>

<p>I get error:
error: project . not found</p>

<p>Can someone tell me why?</p>
