+# Advanced installations
+
+This page contains instructions for setting up multiple countries in
+your Nominatim database. It is assumed that you have already successfully
+installed the Nominatim software itself, if not return to the
+[installation page](Installation.md).
+
+## Importing multiple regions
+
+To import multiple regions in your database, you need to configure and run `utils/import_multiple_regions.sh` file. This script will set up the update directory which has the following structure:
+
+```bash
+update
+ ├── europe
+ │ ├── andorra
+ │ │ └── sequence.state
+ │ └── monaco
+ │ └── sequence.state
+ └── tmp
+ ├── combined.osm.pbf
+ └── europe
+ ├── andorra-latest.osm.pbf
+ └── monaco-latest.osm.pbf
+
+
+```
+
+The `sequence.state` files will contain the sequence ID, which will be used be pyosmium to get updates. The tmp folder is used for import dump.
+
+### Configuring multiple regions
+
+The file `import_multiple_regions.sh` needs to be edited as per your requirement:
+
+1. List of countries. eg:
+
+ COUNTRIES="europe/monaco europe/andorra"
+
+2. Path to Build directory. eg:
+
+ NOMINATIMBUILD="/srv/nominatim/build"
+
+3. Path to Update directory. eg:
+
+ UPDATEDIR="/srv/nominatim/update"
+
+4. Replication URL. eg:
+
+ BASEURL="https://download.geofabrik.de"
+ DOWNCOUNTRYPOSTFIX="-latest.osm.pbf"
+
+!!! tip
+ If your database already exists and you want to add more countries, replace the setting up part
+ `${SETUPFILE} --osm-file ${UPDATEDIR}/tmp/combined.osm.pbf --all 2>&1`
+ with `${UPDATEFILE} --import-file ${UPDATEDIR}/tmp/combined.osm.pbf 2>&1`.
+
+### Setting up multiple regions
+
+Run the following command from your Nominatim directory after configuring the file.
+
+ bash ./utils/import_multiple_regions.sh
+
+## Updating multiple regions
+
+To import multiple regions in your database, you need to configure and run ```utils/update_database.sh```.
+This uses the update directory set up while setting up the DB.
+
+### Configuring multiple regions
+
+The file `update_database.sh` needs to be edited as per your requirement:
+
+1. List of countries. eg:
+
+ COUNTRIES="europe/monaco europe/andorra"
+
+2. Path to Build directory. eg:
+
+ NOMINATIMBUILD="/srv/nominatim/build"
+
+3. Path to Update directory. eg:
+
+ UPDATEDIR="/srv/nominatim/update"
+
+4. Replication URL. eg:
+
+ BASEURL="https://download.geofabrik.de"
+ DOWNCOUNTRYPOSTFIX="-updates"
+
+5. Followup can be set according to your installation. eg: For Photon,
+
+ FOLLOWUP="curl http://localhost:2322/nominatim-update"
+
+ will handle the indexing.
+
+### Updating the database
+
+Run the following command from your Nominatim directory after configuring the file.
+
+ bash ./utils/update_database.sh
+
+This will get diffs from the replication server, import diffs and index the database. The default replication server in the script([Geofabric](https://download.geofabrik.de)) provides daily updates.
