+You might wish to move/rename `config/local.ini.php` to another name and empty (called 'dropping') the database tables, so that you can start fresh.
+
+### Option B: Run the automatic install script
+
+You have the following options to automatically install Friendica:
+- creating a prepared config file (f.e. `prepared.ini.php`)
+- using environment variables (f.e. `MYSQL_HOST`)
+- using options (f.e. `--dbhost <host>`)
+
+You can combine environment variables and options, but be aware that options are prioritized over environment variables.
+
+For more information during the installation, you can use this command line option
+
+ bin/console autoinstall -v
+
+If you wish to include all optional checks, use `-a` like this statement:
+
+ bin/console autoinstall -a
+
+*If* the automatic installation fails for any reason, check the following:
+
+* Does `config/local.ini.php` already exist? If yes, the automatic installation won't start
+* Are the options in the `config/local.ini.php` correct? If not, edit them directly.
+* Is the empty MySQL-database created? If not, create it.
+
+#### B.1: Config file
+
+You can use a prepared config file like [local-sample.ini.php](config/local-sample.ini.php).
+
+Navigate to the main Friendica directory and execute the following command:
+
+ bin/console autoinstall -f <prepared.ini.php>
+
+#### B.2: Environment variables
+
+There are two types of environment variables.
+- those you can use in normal mode too (Currently just **database credentials**)
+- those you can only use during installation (because Friendica will normally ignore it)
+
+You can use the options during installation too and skip some of the environment variables.
+
+**Database credentials**
+
+if you don't use the option `--savedb` during installation, the DB credentials will **not** be saved in the `config/local.ini.php`.
+
+- `MYSQL_HOST` The host of the mysql/mariadb database
+- `MYSQL_PORT` The port of the mysql/mariadb database
+- `MYSQL_USERNAME` The username of the mysql database login (used for mysql)
+- `MYSQL_USER` The username of the mysql database login (used for mariadb)
+- `MYSQL_PASSWORD` The password of the mysql/mariadb database login
+- `MYSQL_DATABASE` The name of the mysql/mariadb database
+
+**Friendica settings**
+
+This variables wont be used at normal Friendica runtime.
+Instead, they get saved into `config/local.ini.php`.
+
+- `FRIENDICA_PHP_PATH` The path of the PHP binary
+- `FRIENDICA_ADMIN_MAIL` The admin email address of Friendica (this email will be used for admin access)
+- `FRIENDICA_TZ` The timezone of Friendica
+- `FRIENDICA_LANG` The langauge of Friendica
