-Hopefully you can start to see how to wrap more complex formatting around the YAML content. When you use a "for" loop, you choose the variable of what to call the list items. The variable you choose to use becomes how you access the properties of each list item. In this case, I decided to use the variable `item`. In order to get each property of the list item, I used `item.subitems`.

 Each list item starts with the hyphen `–`.  You cannot directly access the list item by referring to a mapping. You only loop through the list items. If you wanted to access the list item, you would have to use something like `[1]`, which is how you access the position in an array. You cannot access a list item like you can access a mapping key.
