Give each node a name and expose them so they are listed on the Polkadot [telemetry site](https://telemetry.polkadot.io/#/Local%20Testnet). You'll need two terminal windows open.4950We'll start Alice's substrate node first on default TCP port 30333 with her chain database stored locally at `/tmp/alice`. The bootnode ID of her node is `QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN`, which is generated from the `--node-key` value that we specify below:5152```bash53cargo run -- \54 --base-path /tmp/alice \55 --chain=local \56 --alice \57 --node-key 0000000000000000000000000000000000000000000000000000000000000001 \58 --telemetry-url ws://telemetry.polkadot.io:1024 \59 --validator60```6162In the second terminal, we'll start Bob's substrate node on a different TCP port of 30334, and with his chain database stored locally at `/tmp/bob`. We'll specify a value for the `--bootnodes` option that will connect his node to Alice's bootnode ID on TCP port 30333:6364```bash65cargo run -- \66 --base-path /tmp/bob \67 --bootnodes /ip4/127.0.0.1/tcp/30333/p2p/QmQZ8TjTqeDj3ciwr93EJ95hxfDsb9pEYDizUAbWpigtQN \68 --chain=local \69 --bob \70 --port 30334 \71 --telemetry-url ws://telemetry.polkadot.io:1024 \72 --validator73```7475Additional CLI usage options are available and may be shown by running `cargo run -- --help`.
