# @doc

`@doc` carries documentation metadata attached to a declaration. The text travels with the type or field so tooling can surface it in hovers, generated reference, and other introspection.

```wcl
@block("server") type Server {
  @doc("Listening port; must be free at startup.")
  port: u16
}
```
