 # Updating the Database
 
 There are many different ways to update your Nominatim database.
-The following section describes how to keep it up-to-date with Pyosmium.
-For a list of other methods see the output of `./utils/update.php --help`.

 #### Installing the newest version of Pyosmium

-Nominatim needs a tool called `pyosmium-get-updates` which comes with
-Pyosmium. You need to tell Nominatim where to find it. Add the
-following line to your `settings/local.php`:
-
-    @define('CONST_Pyosmium_Binary', '/home/user/.local/bin/pyosmium-get-changes');
-
-The path above is fine if you used the `--user` parameter with pip.
-Replace `user` with your user name.

 #### Setting up the update process
 
 Next the update needs to be initialised. By default Nominatim is configured
 to update using the global minutely diffs.
 
 If you want a different update source you will need to add some settings
-to `settings/local.php`. For example, to use the daily country extracts
+to `.env`. For example, to use the daily country extracts
 diffs for Ireland from Geofabrik add the following:
 
-    // base URL of the replication service
-    @define('CONST_Replication_Url', 'https://download.geofabrik.de/europe/ireland-and-northern-ireland-updates');
-    // How often upstream publishes diffs
-    @define('CONST_Replication_Update_Interval', '86400');
-    // How long to sleep if no update found yet
-    @define('CONST_Replication_Recheck_Interval', '900');
+    # base URL of the replication service
+    NOMINATIM_REPLICATION_URL="https://download.geofabrik.de/europe/ireland-and-northern-ireland-updates"
+    # How often upstream publishes diffs
+    NOMINATIM_REPLICATION_UPDATE_INTERVAL=86400
+    # How long to sleep if no update found yet
+    NOMINATIM_REPLICATION_RECHECK_INTERVAL=900
 
 To set up the update process now run the following command:
 
-    ./utils/update.php --init-updates
+    nominatim replication --init
 
 It outputs the date where updates will start. Recheck that this date is
 what you expect.
 
-The `--init-updates` command needs to be rerun whenever the replication service
-is changed.

 #### Updating Nominatim
 
 The following command will keep your database constantly up to date:
 
-    ./utils/update.php --import-osmosis-all
-
-(Note that even though the old name "import-osmosis-all" has been kept for
-compatibility reasons, Osmosis is not required to run this - it uses pyosmium
-behind the scenes.)

 If you have imported multiple country extracts and want to keep them
