+You can use the mobile app simulator on your development computer to test your app.
+The connection code will establish communication with your machine over LAN or WAN.
+
+## Set up user authentication
 
 Viam uses [FusionAuth](FusionAuth) for authentication and authorization.
 
 Use the [Viam CLI `auth-app` command](/dev/tools/cli/#auth-app) to register your application with FusionAuth so that you or your users can log into your app with the same credentials they use to log into the [Viam app](https://app.viam.com).

-## Set up authentication
+## Test your app
+
+You can run your app directly on the machine's single-board computer (SBC) if applicable, or you can run it from a separate computer connected to the internet or to the same local network as your machine's SBC or microcontroller.
+The connection code will establish communication with your machine over LAN or WAN.
+
+You can also host your app on a server or hosting service of your choice.
