 ### Prerequisites
 
-- Working Installation of MariaDB Server (version `10.6.25` or later)
-  + MySQL should work too, but there are no guarantees.
+- Working Installation of MySQL 5 or latest MariaDB Server (`mariadb-server` for Debian-based Linux, `XAMPP` for Windows)
 - Python 3.9 or higher
 - PyCharm or similar IDE (optional)
 
 ### Step 1: Preparing Database
 
-To prepare the database, apply the SQL file located in `sql/create_database.sql` to your database server. This is easily accomplished with the MYSQL Workbench, but it can be also done by piping the file into the mariadb-server executable.
-
-After creating the database, apply all patches found in `sql/*_patch.sql` in their numeric order.

+After the  database is created, apply the SQL patches located in `sql/*patch.sql` to support the fallback password- and tournament functionality.
 
 Optionally, you can now execute the script `create_demo_database_content.py`, found in `src/ezgg_lan_manager/helpers`. Be aware that it can be buggy sometimes, especially if you overwrite existing data.
