First Version

Install by copying the contents to your webspace (requires PHP 7.4) and pointing apache to the public folder.
Copy the .env file to .env.local and fill in your database credentials, for example:

DATABASE_URL=mysql://user:password[@127.0.0.1:3306/database_name?serverVersion=mariadb-10.3.23

Also update the APP_SECRET variable to a new random value.

Afterwards run the script bin/console like that:

bin/console doctrine:schema:update --force

Make sure that you use TLS when connecting to your instance, as the crypto libraries in use only work on secure origins.
