+#### Privileged and Unprivileged Nodes
+
+Privileged nodes can process distributed messages from any environment, while unprivileged nodes on registration receive a list of allowed environments. Any message that an unprivileged node process and which comes from an environment to which the node does not have access will result in an error.
+
+By default control servers implementations, provided in this repository (see crates lunatic-control-axum and lunatic-control-submilliseconds), register only privileged nodes with no limitations.
