 ### Software
 
-!!! Warning
-    For larger installations you **must have** PostgreSQL 11+ and PostGIS 3+
-    otherwise import and queries will be slow to the point of being unusable.
-    Query performance has marked improvements with PostgreSQL 13+ and PostGIS 3.2+.

 For running Nominatim:
 
-  * [PostgreSQL](https://www.postgresql.org) (9.6+ will work, 11+ strongly recommended)

+  * [PostgreSQL](https://www.postgresql.org) (12+ will work, 13+ strongly recommended)
