+## Software setup
+
+1. Install [Arduino 1.6.9](https://www.arduino.cc/en/Main/Software)
+1. Install [Arduino ESP8266 core](https://github.com/esp8266/Arduino#installing-with-boards-manager)
+1. Download [FirebaseArduino library](https://github.com/googlesamples/firebase-arduino/archive/master.zip)
+1. Start Arduino
+1. Click `Sketch > Include Library > Add .ZIP Library...`
+1. Choose `firebase-arduino-master.zip` downloaded in step `3.`
+
+## Hardware setup
+
+1. Get a [Wio Link](http://www.seeedstudio.com/wiki/Wio_Link)
+1. Connect:
+  - a [Grove - Vibration Motor](http://www.seeedstudio.com/wiki/Grove_-_Vibration_Motor) on `pin 5`
+  - a [Grove - Light Sensor](http://www.seeedstudio.com/wiki/Grove_-_Light_Sensor) on `pin A0`
+  - a [Grove - Red LED](http://www.seeedstudio.com/wiki/Grove_-_Red_LED) on `pin 12`
+  - a [Grove - Button](http://www.seeedstudio.com/wiki/Grove_-_Button) on `pin 14`
+  - a [Grove - Mini Fan](http://www.seeedstudio.com/wiki/Grove_-_Mini_Fan) on `pin 13`
+
+## Configuration
+
+1. Go to https://www.firebase.com/ and create a new Firebase
+1. Copy the `Firebase Hostname`
+1. Go to `Secrets`
+1. Click `Firebase Secrets > Shows`
+1. Copy the `Firebase Secret`
+1. Start Arduino
+1. Click `File > Examples > firebase-arduino > FirebaseRoom_ESP8266`
+1. Replace `example.firebaseio.com` with the `Firebase Hostname` from step `2.`
+1. Replace `secret_or_token` with `Firebase Secret` from step `5.`
+1. Click `Sketch > Upload`
+
+## Play
+
+1. Go to the Firebase console `Data` section
+1. Set `redlight` to `1` then `0`
+1. Watch the Red LED turn on and off in the room
+1. Same for `cooldown` and `brrr`
+1. Press the push button in the room
+1. Watch the `pushbutton` value change in the Firebase console
+1. Put your hand on the light sensor
+1. Watch the `sunlight` value change in the Firebase console
+
