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.
Documentation
=============
The documentation of the latest development version is in the
`docs/` subdirectory. A HTML version can be found at
https://nominatim.org/release-docs/develop/ .
Installation
============
The latest stable release can be downloaded from https://nominatim.org.
There you can also find [installation instructions for the release](https://nominatim.org/release-docs/latest/admin/Installation), as well as an extensive [Troubleshooting/FAQ section](https://nominatim.org/release-docs/latest/admin/Faq/).
[Detailed installation instructions for current master](https://nominatim.org/release-docs/develop/admin/Installation)

A quick summary of the necessary steps:
1. Create a Python virtualenv and install the packages:

mkdir nominatim-project
cd nominatim-project
../nominatim-venv/bin/nominatim import --osm-file <your planet file>
