+Porting Firefox OS to Rpi is all done by Chris Jones. I just wrote the Gecko APIs that make GPIO possible.

+## Write your own apps
+
+1. Grab this repo: https://github.com/jan-os/janos/tree/gpio
+2. Check out `apps/system/js/my-app.js` for examples
+3. Go on the same network as the device and run `nmap --open -p 5555 192.168.2.*` (if 192.168.2 is your IP range of course) and use the IP in next step
+4. Connect to the device via `adb`: `adb connect 192.168.2.100`
+5. Verify that it works by running `adb logcat`, should see a lot of stuff going on
+6. Run `make install-phone` to update
+7. To debug, use [WebIDE](http://janos.io/articles/first-app.html#debugger)
+
+## Example of the API
+
+Highly experimental, but to open pin 3 for output, set it to HIGH and then release it again:
+
+```js
+navigator.gpio.setPinMode(3, 'output')
+  .then(pin => {
+    pin.writeDigital(true)
+      .then(() => console.log('OK!'))
+      .catch(ex => console.error('NOK!', ex));
+  });
+```
+
+Only does digital pins at the moment.
