+.Sh DESCRIPTION
+.Nm
+is a wrapper command for Mirakurun provided by Nix. It's actually a thin
+wrapper around the
+.Xr npm 1
+command line tool which you can use to invoke npm commands from the Mirakurun
+project directory. The command line arguments are simply passed as-is to
+.Xr npm 1 .
+.Pp
+On NixOS, it is strongly recommended that you enable the mirakurun module
+instead of invoking this command directly to launch Mirakurun. On other
+platforms, run
+.Pp
+.Dl $ mirakurun start
+.Pp
+to start Mirakurun.
