Spade is a work in progress language and so is this documentation. Writing documentation is hard since it is hard to know what details are obvious and what things need more explanation. To make the documentation better, your feedback is invaluable so if you notice anything that is unclear or needs more explanation, please, reach out either via a gitlab issue or on Discord
