title: How do I build sphinx (readthedocs) documentation for Google App Engine projects?
body: <p>I have a Google App Engine project named <a href="https://github.com/samedhi/gaend" rel="nofollow noreferrer">gaend</a>. I am attempting to build better documentation for it using <a href="http://gaend.readthedocs.io/en/latest/" rel="nofollow noreferrer">readthedocs</a>. I have used </p>
  
  <pre><code>&gt; sphinx-quickstart
  </code></pre>
  
  <p>to build my base sphinx project. Followed by</p>
  
  <pre><code>&gt; sphinx-apidoc -o . ../gaend
  </code></pre>
  
  <p>to generate a API list of the project. I then run </p>
  
  <pre><code>sphinx-autobuild . _build/html

  <p>I recognize that the problem is that it does not have access to the Google Cloud SDK. I have had similar issues with running my unit test, and the work around to doing this is in <a href="https://github.com/samedhi/gaend/blob/master/runner.py" rel="nofollow noreferrer">runner.py</a>. However, this relies on having the Google Cloud SDK (with the Python Google App Engine module installed) somewhere on my system. How am I going to get the Google Cloud SDK (and Python GAE) on the <a href="https://readthedocs.org/" rel="nofollow noreferrer">readthedocs</a> server that build my documentation?</p>
