 ### Nominatim API
 
-Nominatim indexes named (or numbered) features with the OSM data set and a subset of other unnamed features (pubs, hotels, churches, etc).
+!!! Attention
+    The current version of Nominatim implements two different search frontends:
+    the old PHP frontend and the new Python frontend. They have a very similar
+    API but differ in some implementation details. These are marked in the
+    documentation as `[Python-only]` or `[PHP-only]`.
 
-Its API has the following endpoints for querying the data:
+    `https://nominatim.openstreetmap.org` implements the **Python frontend**.
+    So users should refer to the **`[Python-only]`** comments.
+
+This section describes the API V1 of the Nominatim web service. The
+service offers the following endpoints:
 
  * __[/search](Search.md)__ - search OSM objects by name or type
  * __[/reverse](Reverse.md)__ - search OSM object by their location
- * __[/lookup](Lookup.md)__ - look up address details for OSM objects by thier ID
- * __/status__ - query the status of the server
+ * __[/lookup](Lookup.md)__ - look up address details for OSM objects by their ID
+ * __[/status](Status.md)__ - query the status of the server
  * __/deletable__ - list objects that have been deleted in OSM but are held
                     back in Nominatim in case the deletion was accidental
  * __/polygons__ - list of broken polygons detected by Nominatim
- * __/details__ - show internal details for an object (for debugging only)
+ * __[/details](Details.md)__ - show internal details for an object (for debugging only)
