+The `solana-localnet` program is provide to easily start a test Solana network
+locally on your machine.  Docker must be installed.  The JSON RPC endpoint of
+the local network is `http://localhost:8899`.
+
+To start, first fetch the latest Docker image by running:
+```bash
+$ npx solana-localnet update
+```
+
+Then run the following command to start the network
+```bash
+$ npx solana-localnet up
+```
+
+While the network is running logs are available with:
+```bash
+$ npx solana-localnet logs -f
+```
+
+Stop the network with:
+```bash
+$ npx solana-localnet up
