+The tiles are available on http://192.168.176.2/ or something like that. Have a look at the docker container to know which is the IP address: there is a message like "Could not reliably determine the server's fully qualified domain name, using 192.168.176.2.". (should be on http://localhost:8080/ though...)
 
+#### Generate tiles from a list
+
+There's a script in utils to generate a list of tiles to be used to generate the tiles.
+
+```bash
+python3 generate-tiles-list.py > tiles.list
+```
+
+Move this `tiles.list` file in the `/tiles/` directory and then run:
+
+```bash
+docker-compose run --rm map generate_tiles
+```
