     This command uses `/tmp/raw-local-chainspec.json` as the location of the sample chain specification file. Be sure the `--chain` command line specifies the path to the raw chain specification you downloaded into a local working directory. This command also uses the default values for the port (`port`) and WebSocket port (`ws-port`). The values are explicitly included here as a reminder to always check these settings. After the node starts, no other nodes on the same local machine can use these ports.
