+netdata is a system for distributed real-time performance and health
+monitoring. It provides unparalleled insights, in real-time, of
+everything happening on the system it runs, using modern interactive
+web dashboards.
+
+Optional dependencies:
+- nodejs (monitoring named and SNMP devices)
+- psycopg2 (monitoring postgres databases)
+- MySQL-python (monitoring MySQL databases)
+
+netdata daemon will run under netdata user and group.
+You need to create the following user/group before building:
+groupadd -g 338 netdata
+useradd -u 338 -g 338 -c \"netdata user\" -s /bin/bash netdata
+
+If you want to run this daemon on every boot:
+chmod +x /etc/rc.d/rc.netdata
+
+Add this line to /etc/rc.d/rc.local:
+if [ -x /etc/rc.d/rc.netdata ]; then
+  /etc/rc.d/rc.netdata start
+fi
+
+To access the dashboards, visit
+http://IP-ADDRESS:19999/
+
+To get the running config file at any time, visit
+http://IP-ADDRESS:19999/netdata.conf

+# HOW TO EDIT THIS FILE:
+# The "handy ruler" below makes it easier to edit a package description.
+# Line up the first '|' above the ':' following the base package name, and
+# the '|' on the right side marks the last column you can put a character in.
+# You must make exactly 11 lines for the formatting to be correct.  It's also
+# customary to leave one space after the ':' except on otherwise blank lines.
