+Blindtest
+=========
+
+Blindtest is a multiplayer musical game (up to 16 simultaneous players). This is a very early version and surely contains bugs.
+
+Gameplay
+--------
+* The main screen plays a 30sec audio sample of a random song
+* 4 possible answers are displayed
+* with their mobile phone, players have to guess who is the singer of the song
+
+Installing
+----------
+* Get the source `git clone git://github.com/mauricesvay/Blindtest.git`
+* `cd Blindtest`
+* Install dependencies (socket.io, express, sqlite3) with `npm install .`
+
+Starting the game
+-----------------
+* `node app.js`
+* open `http://localhost:8080/spectate` in your browser. It is now the main screen.
+* each player can now join the game at `http://MAIN_SCREEN_IP_ADDRESS:8080/`
+* when all players are ready, you can start the game on the main screen. 
+
+Technical details
+-----------------
+* Audio samples and tracks info come from Deezer API
+* Songs are picked randomly among french charts (1956-2012)
+* Real time connection is made with socket.io
+* The app has been tested on a Mac (server), iPhone (client), iPad (client) and is known for working on some Android devices (client).
