+Runs an OpenDHT node, with a CLI (default) or as a daemon (with \fB'-d'\fP or \fB'-s'\fP).
+Commands available in the interactive shell are:
 .EE
     h, help    Print this help message.
     q, quit    Quit the program.

-\fB-n\fP \fInetwork_id\fP
+\fB\-s\fP
+Run the program in service mode (non\-forking daemon).
+.TP
+\fB\-D\fP
+Enables multicast automatic local peer discovery.
+.TP
+\fB\-f\fP \fIfile\fP
+Specify a file path to persist/load the node state.

+\fB\-n\fP \fInetwork_id\fP
 Specify the network id. This let you connect to distinct networks and prevents
 the merge of two different networks (available since OpenDHT v0.6.1).

-\fB-p\fP \fIlocal_port\fP
-Use port \fIlocal_port\fP for the program to bind to.

-\fB-b\fP \fIbootstrap_host\fP[:\fIport\fP]
+\fB\-b\fP \fIbootstrap_host\fP[:\fIport\fP]
 The program needs to be given a node to connect to the network. You use this
