+Contribute to Documentation
+============================
+
+This guide is a reference on how to contribute to ODM2 Documentation effort
+for the many `ODM2 Software Ecosystem <https://github.com/ODM2/odm2-software-ecosystem>`__.
+
+Conventions
+-----------
+
+There are a few conventions that should be followed
+when writing docstrings within the code:
+
+- Docstrings should follow `Google Style Documentation
+<http://sphinxcontrib-napoleon.readthedocs.io/en/latest/example_google.html>`__.
+- Do not say "**defaults to ____**" for any arguments,
+unless the argument needs further explanation.
+The default value is already available in the method/function definition.
+- If function needs to be instantiated, explicitly show in example. See
+`here <https://stackoverflow.com/questions/17134653/difference-between-class-and-instance-methods>`__
+for discussion of class vs instance methods.
+- Provide link to `Controlled Vocabulary <http://vocabulary.odm2.org/>`__
+if an argument needs a CV as value.
+
+Please add any additional conventions that you think should be in place
+within `the github issue #106 <https://github.com/ODM2/ODM2PythonAPI/issues/106>`__.
+
+Pull requests
