-To do this we declare the actions with the `<RemoteAction/>` tag in the `<TreeNodesModel/>`, and add a `host_name` and `host_port` field to it. As a normal action, it also requires to have the `server_name` field set.
-The `host_name` and `host_port` can be set either statically (in the `TreeNodesModel` definition) or dynamically (within the `BehaviorTree` node instance), although we recommend to set it statically to avoid possible runtime errors.
+To do this we declare the actions with the `<RemoteAction/>` and conditions with the `<RemoteCondition/>` tag in the `<TreeNodesModel/>`, and add a `host_name` and `host_port` field to them.
