+# Geocoder for OsmAnd
+
+This is a simple Android app to support the use of the [Nominatim](https://nominatim.org) geocoding API with [OsmAnd](https://osmand.net).
+It accepts a string and queries the Nominatim API to find matches in the OpenStreetMap data.
+The app shows a list of the results returned (a maximum of 10).
+When the user selects an entry from the list, the app sends an intent with a [`geo` URI](https://en.wikipedia.org/wiki/Geo_URI_scheme) specifying the latitude and longitude of the place, which is received by OsmAnd (or perhaps another mapping app).
+
+## Input
+
+I'm not sure exactly what sorts of search strings this application will work with.
+It uses the "free-form" query feature documented [here](https://nominatim.org/release-docs/latest/api/Search/#parameters).
+Looks like it tends to work very well with addresses in the typical format humans use.
+
+## Nominatim API
+
+Please be aware that the app makes requests to the nominatim.org API without rate limiting.
+See [Nominatim's usage policy](https://operations.osmfoundation.org/policies/nominatim) for more information.
