6 Nominatim (from the Latin, 'by name') is a tool to search OpenStreetMap data
7 by name and address (geocoding) and to generate synthetic addresses of
8 OSM points (reverse geocoding). An instance with up-to-date data can be found
9 at https://nominatim.openstreetmap.org. Nominatim is also used as one of the
10 sources for the Search box on the OpenStreetMap home page.
15 The documentation of the latest development version is in the
16 `docs/` subdirectory. A HTML version can be found at
17 https://nominatim.org/release-docs/develop/ .
