+Installation:
+
+1. Create a folder named '_contao_backup' in your contao root directory on target system (webserver)
+2. Copy the file 'contao_backup.php' into '_contao_backup' folder
+3. Open this file on target system and edit DATABASE_NAME, -USER and -PASS according to target database credentials
+4. Optional: edit number of backups (NUM_BACKUPS)
+5. Add 'contao_backup.php' with path to crontab e.g. (every day at 1pm):
+   0       1       *       *       *       php /var/www/vhosts/memap.de/washnroll.memap.de/_contao_backup/contao_backup.php
