+
+
+## GFX Pack Class
+
+The `GfxPack` class deals with RGB backlight and buttons on the GFX Pack. To create one, import the `gfx_pack` module, then define a new `board` variable:
+
+```python
+import gfx_pack
+
+board = gfx_pack.GfxPack()
+```
+
+
+### Switches
+
+The GFX Pack has 5 user switchs located just under the display labeled A to E. The names of these switches in the class are:
+
+`.switch_a`
+
+`.switch_b`
+
+`.switch_c`
+
+`.switch_d`
+
+`.switch_e`
+
+These can be read with the `.is_pressed` method.
+
+```python
+
+if (board.switch_a.is_pressed):
+    print('You pressed Switch A')
+
+if (board.switch_b.is_pressed):
+    print('You pressed Switch B')
+```
+
+
+
+### RGB Backlight
+
+The GFX has an RGB backlight as well as the regular Matrix display backlight to change the colour of the backlight. This is accessed via the following method.
+
+
+`.rgb.set_rgb(r, g, b)`
+
+Where r, g, b are values between 0 and 255
+
+
+example:
+
+
+```python
+
+board.rgb.set_rgb(255, 0, 0)  # Makes the Backlight Red
+
+board.rgb.set_rgb(0, 255, 0)  # Makes the Backlight Blue
+
+board.rgb.set_rgb(0, 0, 255)  # Makes the Backlight Green
+
+```
