Using this KittenBot silicone sleeve is a breeze. First, just stretch the sleeve gently and place it over your micro:bit board. Make sure the white bottom 'bumper' fits well, especially if you're not using the DragonTail breakout. When you want to wear it, use the kitten ears to attach it to your clothes. As for maintenance, you can simply use a damp cloth to wipe it clean when it gets dirty. Avoid using sharp objects near the sleeve to prevent tearing. Also, don't expose it to extreme heat as it might damage the silicone material.
