Nominatim
=========

Nominatim (from the Latin, 'by name') is a tool to search OpenStreetMap data
by name and address (geocoding) and to generate synthetic addresses of
OSM points (reverse geocoding). An instance with up-to-date data can be found
at https://nominatim.openstreetmap.org. Nominatim is also used as one of the
sources for the Search box on the OpenStreetMap home page.

`docs/` subdirectory. A HTML version can be found at
