 If you have an I2P router running on the same machine that is all you need to do.  If you use a custom I2CP host and port, create a file `i2p.properties` and put `i2cp.tcp.host=<host>` and `i2cp.tcp.port=<port>` in there.  On Windows that file should go into `%HOME%\AppData\Roaming\MuWire`, on Mac into `$HOME/Library/Application Support/MuWire` and on Linux `$HOME/.MuWire`
 
-If you do not have an I2P router, pass the following switch to the Java process: `-DembeddedRouter=true`.  This will launch MuWire's embedded router.  Be aware that this causes startup to take a lot longer.

+### 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.
+
+The CLI is under active development and doesn't have all the features of the GUI.
