+## Purpose
 
 I needed a Docker-based environment in which to host AWS python lambda functions for the purpose of testing and building them... python-lambda works well under virtualenv for development, but build and deployment automation require a clean and reproducible environment to operate in. Our CI system already supported Docker as a containerization sytem, so it was the obvious choice.
 
 In order to use this, you will have your project derive its own Dockerfile based on a base python-lambda image corresponding to which version of Python you wish to run.
 
-# Usage
+## Usage
 
 An example of a usable project can be found in the [example/](./example/) directory.  This lambda function takes a JSON input file like the provided [event.json](./example/event.json) and returns an ASCII-art version of the text described in it.  The provided [Dockerfile](./example/Dockerfile) derives from this image and loads the current workspace into the image, then installs dependencies from the [requirements.txt](./example/requirements.txt) file.

+### Python Version
 
 The example Dockerfile uses _:latest_ in the FROM line, which is currently the same as _:python-3.6_, but if you wish to use different python versions you can change this.
