+# Version 1 - 1/19/11 - Initial release
+#
+# Munin plugin to graph the signal strength/quality for a HDHomeRun TV tuner.
+# Developed and tested against a HDHR US Dual model.
+#
+# Requires the hdhomerun_config binary. It can be obtained from
+# http://www.silicondust.com/support/hdhomerun/downloads/linux/
+# Or if you are running Debian/Ubuntu:
+# apt-get install hdhomerun-config
+#
+# Place the hdhomerun_ script in your munin plugins directory (usually
+# /usr/share/munin/plugins) and create symlinks of the format
+# "hdhomerun_<deviceid>_tuner<number>", such as hdhomerun_123456_tuner0.
+# The deviceid can be obtained by running "hdhomerun_config discover".
+# Alternatively, the script supports the suggest option which will
+# scan for all HDHomeRun devices on the network and set up the symlinks.
+# To do this, run:
+#
+# munin-node-configure --shell | grep hdhomerun | bash
+#
+# Note: It will assume you have a dual tuner model and set up links
+# for tuner0 and tuner1. If you have a single tuner model, just delete
+# the tuner1 link.
