Instead of this repository it is prefered to use asyncio branch (https://github.com/ilex/motorengine/tree/asyncio) of motorengine as it much more compatible with motorengine. Instead of aiomotorengine use motorengine.aiomotorengine.
aiomotorengine is a port of the motorengine which uses Motor for asynchronous access to MongoDB and Asyncio's event loop instead of Tornado's one. It also uses new syntax async def and await for asynchronous code introduced in python 3.5
To install AIOMotorEngine use pip:
$ pip install https://github.com/ilex/aiomotorengine/archive/master.zip
Find out more by reading aiomotorengine documentation.
