title: Android protobuf nano documentation
body: <p>I am trying to reduce the number of methods that are generated by Google proto-buf and one of the alternatives is to use proto-buf nano. However I found no documentation on how to use it. Except the <a href="https://github.com/android/platform_external_protobuf/tree/master/java/src/main/java/com/google/protobuf/nano" rel="nofollow">package link</a>, I can't find anything on how to generate java files from proto files using nano.</p>
  
  <p>So the question is straight-forward: how to use google proto nano in order to generate java classes from proto files and how to use them in a project?</p>
