+=head1 NAME
+
+fastd_ - Plugin to monitor fastd uptime, peers and traffic
+
+=head1 CONFIGURATION
+
+Set user and group to have access to the socket
+Set path to socketfile if not /tmp/fastd.sock
+
+    [fastd_*]
+    user fastd
+    group fastd
+    env.socketfile /tmp/fastd.sock
+
+=head1 USAGE
+
+Link this plugin to /etc/munin/plugins/ with the type of graph (uptime, peers, traffic)
+append to the linkname, ie: /etc/munin/plugins/fastd_peers
+
+After creating the links, restart munin-node. Don't forget to configure the plugin!
