+can2joy
+========
+
+Use your car as a life-sized controller for your racing game on Linux!
+
+
+Compatible cars
+----------------
+
+At the moment, only the following model has been tested:
+
+ - Volkswagen Golf Mk 6
+
+
+Compatible adapters
+--------------------
+
+Any CAN adapter supported by Linux' Socketcan stack should work.
+
+It has been tested using:
+
+ - 8devices USB2CAN
+
+
+Compatible games
+-----------------
+
+Any game should work.
+
+However my favorite demo tool is Need For Speed III, running in Wine.
+
+Yes, a 1998 era Windows game, running on Wine on Linux, steered by an
+actual car.
+
+
+How to connect this to a car
+-----------------------------
+
+In order for can2joy to receive updates about the wheel, it needs to be
+connected to a place in the car where this information flows freely.
+
+BE AWARE THAT CONNECTING FOREIGN EQUIPMENT TO YOUR CAR IS ENTIRELY AT
+YOUR OWN RISK. YOU'RE ON YOUR OWN IF YOUR CAR CRASHES, BURNS, EXPLODES,
+OR DRIVES OVER YOUR CAT.
+
+In a VW Golf Mk6, the OBD II connector is silent unless information is
+requested. A relatively safe way of accessing this is the Infotainment
+CAN bus, which connects to the radio/head unit, the Bluetooth module,
+and the MDI/Media-In module. It's up to you to figure out how to connect
+the car's CAN-High, CAN-Low, and GND to your CAN adapter.
+
+On the software side, all we have to do there is to listen passively:
+
+ ip link set can0 down
+ ip link set can0 type can bitrate 100000
+ ip link set can0 type can listen-only on
+ ip link set can0 up
+
+Then, you're ready to run can2joy.
+
+
+How to run can2joy
+-------------------
+
+First, ensure that:
+ - your Linux kernel supports uinput
+ - the uinput module is loaded
+ - /dev/uinput exists
+ - your user has access to /dev/uinput
+
+Then:
+
+ make
+ ./can2joy can0
+
+...where can0 is to be replaced by the CAN interface you've
+connected to your car.
