Namespace

namespace Platformer
{
    //class
}

Platformer namespace is used for all scripts to avoid conflicts with your scripts.

Editing

All code has comments describing each action, so editing is easy

namespace Platformer
{
    public class Custom_Item : PickUpItem
    {
        protected override void OnPickedUp()
        {
            /////////////////////////////////////////////////Here your logic

            Debug.Log("It's my logic");

            /////////////////////////////////////////////////
        }
    }
}
