+### Usage
+
+Declare I2C bus and add this module in your main class.
+
+```python
+from kmk.modules.easypoint import Easypoint
+import busio as io
+
+i2c = busio.I2C(scl=board.GP1, sda=board.GP0)
+
+easypoint = Easypoint(i2c, address=0x40)
+keyboard.modules.append(easypoint)
+```
+
+Further configuring the AS5013 involved x/y-offset, and deadzone.
+
+```python
+easypoint = Easypoint(i2c, address=0x40, y_offset=Y_OFFSET, x_offset=X_OFFSET, dead_x=DEAD_X, dead_y=DEAD_Y)
+```
