+
+Notes:
+
+ - `ROSETTA_TUNNEL_HOST` must not include http:// or https://
+ - `ROSETTA_REGISTRY_HOST` should be set to the same value as `ROSETTA_HOST` for production scenarios, in order to be secured unders SSL. The `standaloneworker` is configured to treat the following hosts (and ports) as unsecure registies, where it can connect without a valid certificate: `proxy:5000`,`dregistry:5000` and `rosetta.platform:5000`.
+ - `ROSETTA_WEBAPP_HOST` is used for let the agent know where to connect, and it is differentiated from `ROSETTA_HOST` as it can be on an internal Docker network. It is indeed defaulted to the `webapp` container IP address.
+
+
+
+### User types 
+In Rosetta there are two user types: standard users and power users. Their type is set in their user profile, and only power users can:
 
    - set custom task passwords
    - choose task access methods other than the default one (bypassing HTTP proxy + auth)
