Question

Please help me to make a newbie understandable explanation:

1. When should a numbered list be used in text?
   
2. When should you use a bulleted list?
   
3. When is a list inappropriate?
   

And then the employee realized that I love lists in articles, and now he turned each paragraph into lists. Makes a subtitle, such as "What are loans?" and list each offer as a separate item.
Where can I find a good explanation of what they are used for / when should lists be used?
