 1. Run the lightwalletd frontend with the following and your server's hostname:
-    ```shell script
-    go run cmd/server/main.go -bind-addr your_host.net:9067 -conf-file /home/YOUR_USERNAME_Running_Hushd/.komodo/HUSH3/HUSH3.conf -no-tls
     ```
+    ./start.sh
+    ```
+
+If you see the following error `"Can't create data directory: /var/lib/lightwalletd"` you need to set the correct user permissions:
 
-    Note: Above we use the "-no-tls" option as we are using NGINX as a reverse proxy and letting it handle the TLS authentication for us.
+```
+sudo chown -R $USER:$USER /var/lib/lightwalletd
+sudo chmod -R 755 /var/lib/lightwalletd
+```
 
     Note: You can configure lightwalletd to handle its own TLS authentication, but you will have to consult the [lightwalletd documentation](https://git.hush.is/hush/lightwalletd) for that setup.
