+=head1 NAME
+
+pmdanfsclient - nfs client statistics performance metrics domain agent (PMDA)
+
+=head1 DESCRIPTION
+
+B<pmdanfsclient> is a Performance Metrics Domain Agent (PMDA) which exports
+metric values from the /proc/self/mountstats interface to provide information
+on nfs mounts.
+
+=head1 INSTALLATION
+
+If you want access to the names and values for the nfsclient performance
+metrics, do the following as root:
+
+        # cd $PCP_PMDAS_DIR/nfsclient
+        # ./Install
+
+If you want to undo the installation, do the following as root:
+
+        # cd $PCP_PMDAS_DIR/nfsclient
+        # ./Remove
+
+B<pmdanfsclient> is launched by pmcd(1) and should never be executed
+directly.  The Install and Remove scripts notify pmcd(1) when
+the agent is installed or removed.
