Using your KittenBot Silicone Sleeve is a breeze. Just gently stretch the sleeve and place it over your micro:bit board. The white bottom 'bumper' can be added when you're not using the DragonTail breakout. When the LEDs on your micro:bit light up, you'll see the red light shine through the thin rubber. To wear it, use the kitten ears to attach it to your clothes or a bag. As for maintenance, simply wipe it with a soft, damp cloth if it gets dirty. Avoid using harsh chemicals as they might damage the silicone. Also, don't pull the sleeve too hard to prevent tearing.
