+Cronjob for updating DMR IDs
+============================
+You can use the included script to update the DMR IDs periodically. Copy the file updateDMRIDs to /etc/cron.d/ and updateDMRIDs.sh to /var/www. The paths may have to be aligned to your system architecture. The Update script will then be executed once every 24 hours at 3:30. For security considerations please make sure that the cron folder is not copied to your web server's www root directory.
