 - Create a new ProxyVM named `mirage-firewall` to run the unikernel.
 - You can use any template, and make it standalone or not. It doesn’t matter, since we don’t use the hard disk.

   - Turn off memory balancing and set the memory to 32 MB or so (you might have to fight a bit with the Qubes GUI to get it this low).
   - Set VCPUs (number of virtual CPUs) to 1.
 
-You can run `mirage-firewall` alongside your existing `sys-firewall` and you can choose which AppVMs use which firewall using the GUI.
-To configure an AppVM to use it, go to the app VM's settings in the GUI and change its `NetVM` from `default (sys-firewall)` to `mirage-firewall`. Alternatively, you can configure `mirage-firewall` to be your default firewall VM.

+```
+qvm-prefs --set my-app-vm netvm mirage-firewall

+### Easy deployment for developers
+
+For development, use the [test-mirage][] scripts to deploy the unikernel (`qubes_firewall.xen`) from your development AppVM.
+This takes a little more setting up the first time, but will be much quicker after that. e.g.
 
     $ test-mirage qubes_firewall.xen mirage-firewall
