Minecraft: Simple super compact Wool Farm! (1.21) [Quick tutorial]

How to create a simple compact Sheep Farm in Minecraft! A simple quick tutorial that tells you all you need!

This farm functions by detecting when the sheep eats grass and then dispenses shears onto it. This is because whenever a sheep eats grass, it regrows its wool and is thus able to be sheared again.
