-## Installing Tiger housenumber data for the US
-
-Nominatim is able to use the official [TIGER](https://www.census.gov/geographies/mapping-files/time-series/geo/tiger-line-file.html)
-address set to complement the OSM house number data in the US. You can add
-TIGER data to your own Nominatim instance by following these steps. The
-entire US adds about 10GB to your database.
-
-  1. Get preprocessed TIGER 2020 data:
-
-        cd $PROJECT_DIR
-        wget https://nominatim.org/data/tiger2020-nominatim-preprocessed.tar.gz
-
-  2. Import the data into your Nominatim database:
-
-        nominatim add-data --tiger-data tiger2020-nominatim-preprocessed.tar.gz
-
-  3. Enable use of the Tiger data in your `.env` by adding:
-
-        echo NOMINATIM_USE_US_TIGER_DATA=yes >> .env
-
-  4. Apply the new settings:
-
-        nominatim refresh --functions

-See the [developer's guide](../develop/data-sources.md#us-census-tiger) for more
-information on how the data got preprocessed.
