 ### 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)

-#### Building in legacy CMake mode
-
-!!! warning
-    Installing Nominatim through CMake is now deprecated. The infrastructure
-    will be removed in Nominatim 5.0. Please switch to pip installation.
-
-The code must be built in a separate directory. Create the directory and
-change into it.
-
-```
-mkdir build
-cd build
-```
-
-Nominatim uses cmake and make for building. Assuming that you have created the
-build at the same level as the Nominatim source directory run:
-
-```
-cmake ../Nominatim
-make
-sudo make install
-```
-
-!!! warning
-    The default installation no longer compiles the PostgreSQL module that
-    is needed for the legacy tokenizer from older Nominatim versions. If you
-    are upgrading an older database or want to run the
-    [legacy tokenizer](../customize/Tokenizers.md#legacy-tokenizer) for
-    some other reason, you need to enable the PostgreSQL module via
-    cmake: `cmake -DBUILD_MODULE=on ../Nominatim`. To compile the module
-    you need to have the server development headers for PostgreSQL installed.
-    On Ubuntu/Debian run: `sudo apt install postgresql-server-dev-<postgresql version>`
-    The legacy tokenizer is deprecated and will be removed in Nominatim 5.0
-
-
-Nominatim installs itself into `/usr/local` per default. To choose a different
-installation directory add `-DCMAKE_INSTALL_PREFIX=<install root>` to the
-cmake command. Make sure that the `bin` directory is available in your path
-in that case, e.g.
-
-```
-export PATH=<install root>/bin:$PATH
-```
 
 Now continue with [importing the database](Import.md).
