 The `Deref` trait allows an instance of the smart pointer struct to behave like a reference so you can write your code to with either references or smart pointers. [Section Link Here](./Deref%20Trait.md)
 
-The `Drop` trait allows you to customize the code that is run when an instance of the smart pointer goes out of scope.

 We will go over both traits and demonstrate why they are improtant to smart pointers.

 The ones we will cover are the most common smart pointers in the std library:
 - [`Box<T>` for allocating values on the heap](./Using%20Box%20on%20the%20Heap.md)
-- `Rc<T>`, a reference counting type that enables multiple ownership
+- `Rc<T>`, a reference counting type that enables multiple ownership [Section Link Here](./Reference%20Counter%20Smart%20Pointer.md)
 - `Ref<T>` and `RefMut<T>` this is accessed through `RefCell<T>`, a type that enforces the borrowing rules at runtime instead of compile time
 
 In additon we will also cover *interior mutability* patter where an immutable tpye exposes an API for mutating an interior value.
