### Check the docs

Now, if you check the docs, they will show all the additional metadata:

### Order of tags

The order of each tag metadata dictionary also defines the order shown in the docs UI.

For example, even though `users` would go after `items` in alphabetical order, it is shown before them, because we added their metadata as the first dictionary in the list.

// Go.
package generics

// Variables with an instantiated type should be shown.
var X Type[int]

// Parameterized types should be shown.
type Type[P any] struct {
	Field P
}

// Constructors for parameterized types should be shown.
func Constructor[lowerCase any]() Type[lowerCase] {
	return Type[lowerCase]{}
}
