r markdown - Automatically number sections in RMarkdown

Question

I am trying to create a report in R markdown that has sections ordered

1. Section 1 Header

   1.1 sub section 1

   1.2 sub section 3

2. Section 2 Header

   2.1

   2.2 sub section

     2.2.1 another sub section
   

Is there a way get R markdown to generate an ordered list like this?

---

# Main Section

## 2nd Level

### 3rd Level

And voilá, your sections are numbered:
