 ## Limitations and caveats
 
+- Routing packets through an extra pair of applications may slightly increase latency compared to direct connections. In my tests, added latency appeared to be 10..20ms, depending on the game.
 - Only supports two players per session   
 	(though you can technically run multiple copies of the tool on host's end)
 - Does not support forwarding socket errors - if something goes wrong, you'll get either a generic "connection closed" or a "connection timeout". Inspecting the tool's output may reveal the actual problem.

+## Command-line arguments
+
+You may run the tool from CLI (Command Prompt or PowerShell on Windows, Terminal on Mac/Linux, etc.) to avoid having to re-enter details every time you run the tool. Supported arguments are as following:
+
+- `--server`: Automatically enters server mode
+- `--client`: Automatically enters client mode
+- `--tcp`: Automatically uses TCP protocol
+- `--udp`: Automatically uses UDP protocol
+- `--host <ip>`: Uses the specified IP address to host on/connect to (e.g. `--host 127.0.0.1`)
+- `--port <number>`: Uses the specified IP address to host on/connect to (e.g. `--port 5394`)
