+.Sh DESCRIPTION
+Mycorrhiza Wiki is a lightweight wiki engine. It uses Git repositories as a
+means of keeping history, and provides a custom-made markup language called
+Mycomarkup for authoring pages. The only runtime dependency is the
+.Nm git
+command-line program. The web interface provides viewing and editing
+capabilities, history, administration, and simple search.
+.Pp
+The
+.Nm
+program serves a web interface for the wiki located in
+.Ar wiki-path ,
+on the address specified by
+.Ar addr
+or the configuration file. If the wiki directory
+does not exist, it's automatically created, and the configuration is populated
+with default values. The default configuration file
+.Pq Pa config.ini
+includes comments describing different options.
+.Pp
+The options are as follows:
+.Bl -tag -width Ds
+.It Fl help
+Display help.
+.It Fl create-admin Ar username
+Create a new user with name set to
+.Ar username ,
+and give them administrative rights. The password is prompted in the terminal.
+.It Fl listen-addr Ar addr
+Listen on
+.Ar addr
+instead of the value specified in the configuration file.
