@jeff-schutt - Can you help coordinate a review with the next week?
@JPEWdev - I don't know if you've had a chance look at the embedded examples in the markdown files

Planning to review all the security examples in the call this Wednesday. Will open a PR with any changes then.

Closing this issue - we reviewed and fixed a few small misprints at the last call (via #709)
