-This program runs a simple OpenDHT node in an interactive way. If you rather
-want to run the node in daemon mode, option \fB'-d'\fP is provided. When running
-in the interactive shell, you benefit from the readline capabilities for writing
-your commands such as command history. Here are the available commands in the

-
+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.

+.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-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
 option to provide the ip address of that node.
