+Installing
+----------
+
+**On most systems, just copy the "hardware" and "libraries" folders into your Arduino folder.**
+
+On Windows you can find this folder in the "My Documents" folder. On most unixes in your home folder.
+
+On some picky linux systems you might need to do the following:
+```
+sudo mkdir /usr/share/arduino/hardware/arduino/avr/variants/ijduino
+sudo cp hardware/ijhack/avr/variants/ijduino/pins_arduino.h /usr/share/arduino/hardware/arduino/avr/variants/ijduino/
+sudo cat hardware/ijhack/avr/boards.txt >> /usr/share/arduino/hardware/arduino/avr/boards.txt
+```
+
+On Mac OS X just copy into the Application folder:
+```
+cp -r hardware/ijhack /Applications/Arduino.app/Contents/Java/hardware
+cp -r libraries/* /Applications/Arduino.app/Contents/Java/libraries
+```

+
+You probably need to add a udev rule to get this working. Place the following at `/etc/udev/rules.d/99-usbasp.rules`
+
+```
+SUBSYSTEMS=="usb", ATTRS{idVendor}=="16c0", ATTRS{idProduct}=="05dc", GROUP="users", MODE="0666"
+```
+Then run `udevadm trigger` to reload the udev rules.
