+### Running the CLI
+
+Look inside `cli-lanterna/build/distributions`.  Untar/unzip one of the `shadow` files and then run the jar contained inside by typing `java -jar cli-lanterna-x.y.z.jar` in a terminal.  The CLI will ask you about the router host and port on startup, no need to edit any files.  However, the CLI does not have an options window yet, so if you need to change any options you will need to edit the configuration files.  The CLI options are documented here https://github.com/zlatinb/muwire/wiki/CLI-Configuration-Options
+
+The CLI is under active development and doesn't have all the features of the GUI.
