Add basic usage instructions

[imikejackson]

Problem to solve

There are no actual usage instructions?

Intended users

Everyone

Further details

I would expect the ReadMe.adoc to contain something along the lines of "python scripts/some_python_script.py

Proposal

Documentation

Testing

None. More people will use this.

What does success look like, and how can we measure that?

Hi there. The wiki contains a good deal of usage information. While we know it could use some updates, the instructions on use are there.
