What should the deployment folder contain?

This folder is a catch-all section to put all development-related docs for your module. Examples of what should be here:

1. What all the deployment configurations are, and how to set them - for example, what are all the environment variables for your service.
2. What does each configuration option do?
3. Recommended values under different circumstances, especially recommendations for production settings.

As always, if you need to split your deployment information up into multiple files, feel free to add more files to this section.
