+
+## Description
+
+Arborist is a monitoring toolkit that follows the UNIX philosophy
+of small parts and loose coupling for stability, reliability, and
+customizability.
+
+This adds fping sweeping support to Arborist monitoring, which is an
+efficient means to check the ICMP reachability of many, many hosts
+simultaneously.
+
+It requires the fping binary to be installed in your path.  Use your
+package manager of choice.
+
+
+## Prerequisites
+
+* Ruby 2.2 or better
+
+
+## Installation
+
+    $ gem install arborist-fping
+
+
+## Usage
+
+In this example, we're using ICMP reachability as the method to
+determine if a host node is available/present on network.
+
+	Arborist::Host( 'example' ) do
+		description "Example host"
+		address     '10.6.0.169'
+	end
+
+
+From a monitor file, require this library, and exec() to fping.  We'll
+record RTT per node in this example with the -e flag, and lower the
+timeout-per-host:
+
+	require 'arborist/monitor/fping'
+
+	Arborist::Monitor 'ping check' do
+		every 10.seconds
+		match type: 'host'
+		include_down true
+		use :addresses
+		exec 'fping', '-e', '-t', '150'
+		exec_callbacks( Arborist::Monitor::FPing )
+	end
+
+That's it.
