     - using `--password` is possible instead of private key, but private key is preferred
 - `--wait_syncing` so CLI waits until Ethereum node is fully synced
-- `--start_port 25000` and `--last_port 25010` denote ports where apps (workers) will be hosted. 25000:25010 is inclusive, so 10 workers could be started on such a node
+- `--api_port 25000` specifies the main port of the Fluence node, so other nodes and users know where to connect 
+- `--capacity 10` limits number of apps that could be run on the node by 10
