+3. Add buttons and axes in `setup()` with the `Add*` functions from `Joystick.h`. Call `joystick.Update()` in your `loop()` function. Also call `joystick.Init()` during `setup()`.
 4. Upload the sketch, connect to the serial monitor (at 115200 baud) and test the buttons.
 5. Set the joystick's `debug` parameter to `false` and re-upload the sketch. The arduino will NOT work in joystick mode with debug set to `true`!

-### Advanced usage: multiplexers
+### Advanced usage: multiplexers, matrices
 
-If you need more buttons than your board has pins, multiplexers (such as [this one](https://www.sparkfun.com/products/13906) and [this one](https://www.sparkfun.com/products/9056)) are a popular solution. This library supports multiplexers! To use them, you need to do some extra work.
-
-Call the `AddMux()` method and pass it the pins the multiplexer is connected to. You'll need to `#include <Mux.h>` to access `admux::Pinset`. `AddMux()` will return a `mux_id` for subsequently passing to `AddButton()`. The `pin` parameter for all multiplexed buttons should be the same as the multiplexer's `signal_pin`.
+If you need more buttons than your board has pins, this library supports keyboard-style scan matrices as well as multiplexers. **(FIXME: multiplexers aren't working yet)** See the example sketch in the `example/` directory for usage details. Note that, for matrices, the *rows* are the inputs that will be read, and the *columns* are the outputs that will sink the current. Current should flow (via diodes) from the rows to the columns. See the `example.simu` SimulIDE file for an example circuit.
