-
-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
-interactive shell:
-
+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\-\-save\-identity\fP \fIfile\fP
+Save generated identity (certificate and private key) to given file prefix.
+.TP
+\fB\-\-certificate\fP \fIfile\fP
+Load identity certificate from given file.
+.TP
+\fB\-\-privkey\fP \fIfile\fP
+Load identity private key from given file.
+.TP
+\fB\-\-privkey\-password\fP \fIpassword\fP
+Password to use for private key encryption or decryption (optional).
+.TP
+\fB\-d\fP
 Run the program in daemon mode (will fork in the background).
-
 .TP
-\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.
+.TP
+\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).
-
 .TP
-\fB-p\fP \fIlocal_port\fP
-Use port \fIlocal_port\fP for the program to bind to.
-
+\fB\-p\fP \fIlocal_port\fP
+Use UDP port \fIlocal_port\fP for the program to bind to.
 .TP
-\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.
