 We'll need to create a service called `test.Add` with its own definition and policy file in dom0.
-In dom0 add the following test to `/etc/qubes-rpc/policy/test.Add`:
-
-      $anyvm $anyvm ask
-
 Now we need to define what the service does.
-In this case, it should call our additing script.
+In this case, it should call our addition script.
 We define the service with another one-line file, `/etc/qubes-rpc/test.Add`:
 
-      /usr/bin/our_test_add_server
+    /usr/bin/our_test_add_server
+
+The adminstrative domain will direct traffic based on the current RPC policies.
+In dom0, create a file at `/etc/qubes-rpc/policy/test.Add` containing the following:
+
+    $anyvm $anyvm ask
+
+This will allow our client and server to communicate.
 
 Before we make the call, ensure that the client and server scripts have executable permissions.
-Now, invoke the RPC service!
+Finally, invoke the RPC service.

 We should get "3" as answer.
 (dom0 will ask for confirmation first.)
