+Now you can try out your installation by executing a simple query on the
+command line:
+
+``` sh
+nominatim search --query Berlin
+```
+
+or, when you have a reverse-only installation:
+
+``` sh
+nominatim reverse --lat 51 --lon 45
+```
+
+If you want to run Nominatim as a service, you need to make a choice between
+running the traditional PHP frontend or the new experimental Python frontend.
+Make sure you have installed the right packages as per
+[Installation](Installation.md#software).
+
+#### Testing the PHP frontend
+
+You can run a small test server with the PHP frontend like this:
```sh
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`.

+You can also run a search query, e.g. `http://localhost:8088/search.php?q=Berlin`
+or, for reverse-only installations a reverse query,
+e.g. `http://localhost:8088/reverse.php?lat=27.1750090510034&lon=78.04209025`.
+
+Do not use this test server in production.
+To run Nominatim via webservers like Apache or nginx, please continue reading
+[Deploy the PHP frontend](Deployment-PHP.md).
+
+#### 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 --engine falcon
+```
+
+or
+
+``` 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`.

Fast disks are essential. Using NVME disks is recommended.
Even on a well configured machine the import of a full planet takes
-around 2 days. On traditional spinning disks, 7-8 days are more realistic.

## Tuning the PostgreSQL database
and even reduce `autovacuum_work_mem` further. This will reduce the amount
of memory that autovacuum takes away from the import process.
-For the initial import, you should also set:
-
- fsync = off
- full_page_writes = off
-
-Don't forget to re-enable them after the initial import or you risk database
-corruption.
