Is your feature request related to a problem? Please describe.
The samples/python/agents/dice_agent_rest folder doesn’t currently have a README.
Describe the solution you'd like
I’d like to add a README covering prerequisites, configuration (DICE_AGENT_URL), and how to run the REST dice client, including how it relates to dice_agent_grpc.
If this sounds good, I can open a PR with the new README.
