What are preconditions and how do they work?

Preconditions are classes that will determine whether or not a command should be ran according to certain conditions. Sapphire has many built in preconditions ready for use that are outlined in the coming pages, such as for creating cooldowns, restricting channel types, handling permissions, and filtering nsfw channels. However, we also provide an easy system for you to create your own preconditions, which you can learn how to use on the next page.
