Create a simulated bucket, add a sample object, then list and delete objects.
Create a simulated DynamoDB table, put an item, then get it back or query by key prefix.
Pick a service and operation in the CLI builder, fill in parameters, and copy the generated command.
Browse the 132-service coverage reference to see what an emulator of this kind covers.
Reset the simulation any time to return to the seeded demo buckets and tables.
