[austinlparker]

With #872 merged, we have several docs updates that need to be done. See #872 for details.

Hello @austinlparker, I would like to be assigned this issue to update the document. Can you kindly provide more context on the project? Thank you.

@Caritajoe18 the demo can be run with fewer components deployed, consuming significantly less memory. I can't remember all the changes so that should be documented. This is the make target that runs it. You can compare docker-compose.yml and docker-compose-minimal.yml to see all the differences.
