Tutorials throughly walk you through and teach you how to build semi-advanced devices, basically anything which is too big/complex for Quick & Easy goes here. These videos always include a world download in the video description.
Quick & Easy videos introduce small yet extremely useful resource friendly gadgets, which you can build in 2 minutes at most. These videos might not always include a world download due to the fact that they're so easy to build.
Demonstrations are videos, where I showcase a device, but don't do a tutorial about it due its complexity, resource heaviness or if it's a proof of concept. These videos always have a world download in the video description.
