Update README in derivatives

[justinlittman]

Out of date.

Errors include:

• Need to add region parameter to commands.
• Example is for rebuild action, which is no longer supported.
• Instructions are for single lambda, while now split into multiple lambdas.

Also, would be helpful to include instructions on how to view lambda output (by viewing lambda container logs).

Still compiling notes for this ticket. Not yet ready for work.

Are we still waiting for more changes or can we work on this?

[justinlittman]

I think this is ready for work.

@justinlittman I believe this is complete. However I did not "add region parameter to commands" as I did not find it necessary:

@justinlittman Do you have a region set in your ~/.aws/config ?

[justinlittman]

No, I don't.
