+### Nominatim prefixes
+
+I18n keys under the `geocoder.search_osm_nominatim` keyspace are managed by the
+Nominatim maintainers. From time to time they run stats over the Nominatim
+database, and update the list of available keys manually.
+
+Adding or removing keys to this list is therefore discouraged, but contributions
+to the descriptive texts are welcome.
