 The parameter type needs to be a reference to a `Properties` type (ex. `props: &MyProps`).
 If the function doesn't have any parameters the resulting component doesn't accept any props.
 
-The attribute doesn't replace your original function with a component. You need to provide a name as an input to the attribute which will be the identifier of the component.
+Just mark the component with the attribute (also aliased as `#[fc]`). The component will be named after the function.
