+# On a Linux based system, such as a Raspberry Pi, this script will perform all  
+# the steps required to maintain the YSFHosts.txt (or similar) file for you.
+#
+# It is designed to run from crontab and will download the YSFHosts from the 
+# master ysfreflector.de database and optionally keep a backup of previously
+# created files for you.
+#
+# It will also prune the number of backup files according to a value specified
+# by you in the configuration below.
+#
+# When done, it will restart YSFGateway to make the Hosts changes take effect.
+#
+# To install in root's crontab use the command ...
+#
+#     sudo crontab -e
+#
+# ... and add the following line to the bottom of the file ...
+#
+#     0  0  *  *  *  /path/to/script/DMRIDUpdate.sh 1>/dev/null 2>&1
+#
+# ... where /path/to/script/ should be replaced by the path to this script.
