 ## Coding Style and Conventions
 
+Here are some coding conventions to keep in mind:
+ 
+* ``Sk.ffi.remapToJs`` and ``Sk.ffi.remapToPy`` are your friends.  They take care of the details 
+of going from a Python type to a Javascript type and vice versa.  They are smart enough to work
+with common types and even work well recursively converting containers.  ``Sk.ffi.remapToJs`` is 
+**definitely preferred** over  ``foo.v``  
+* Use the ``pyCheckArgs`` function at the beginning of anything that will be exposed to a Python programmer.
+* Check the types of arguments when you know what they must be.
+* Explicitly return ``Sk.builtin.null.null$`` for functions and methds that should return ``None``
+* If you are adding a module or package to the library, respect the package/module conventions.
+    * modules should be named ``foo.js`` or ``foo.py`` 
+    * packages should be a directory with an ``__init__.js`` or ``__init__.py`` file, and possibly additional modules.

 In summer of 2014, we adopted the following style and conventions for our code:
 
 * Braces:  One True Brace style -- that means open braces go on the same line as the
