+If you want to run Nominatim as a service, you need to make a choice between
+running the modern Python frontend and the legacy PHP frontend.
+Make sure you have installed the right packages as per
+[Installation](Installation.md#software).
+
+#### Testing the Python frontend
+
+To run the test server against the Python frontend, you must choose a
+web framework to use, either starlette or falcon. Make sure the appropriate
+packages are installed. Then run
+
+``` sh

 nominatim serve
 ```
 
 nominatim serve
 ```
 

-This runs a small test server normally used for development. You can use it
-to verify that your installation is working. Go to
-`http://localhost:8088/status.php` and you should see the message `OK`.
-You can also run a search query, e.g. `http://localhost:8088/search.php?q=Berlin`.
+or, if you prefer to use Starlette instead of Falcon as webserver,
+
+``` sh
+nominatim serve --engine starlette
+```

 
 

-Note that search query is not supported for reverse-only imports. You can run a
-reverse query, e.g. `http://localhost:8088/reverse.php?lat=27.1750090510034&lon=78.04209025`.
