 ## Command line arguments
 
-```
-Usage: servicepoint-simulator [OPTIONS]
-
-Options:
-      --bind <BIND>  address and port to bind to [default: 0.0.0.0:2342]
-  -f, --font <FONT>  The name of the font family to use. This defaults to the system monospace font.
-  -s, --spacers      add spacers between tile rows to simulate gaps in real display
-  -r, --red          Use the red color channel
-  -g, --green        Use the green color channel
-  -b, --blue         Use the blue color channel
-  -v, --verbose      Set default log level lower. You can also change this via the RUST_LOG environment variable.
-  -h, --help         Print help
-```
+The application binds to `0.0.0.0:2342` by default (`./servicepoint-simulator --bind host:port` to change this).
