1. This is the first thing in the ordered list
2. This is the second thing which will have a nested list beneath
• First in the nested sub list
• Second in the nested sub list
• Third in the nested sub list
• Fourth in the nested sub list
3. Now I am back to the original list. Note that I ended both the ul and the li with the ul under it on the line above
4. Another line in the main list
