You can add headers and sub-headers to your document with Markdown. Two syntaxes allow you to insert headers with up to six different levels. You can write headers of level 1 and 2 using the "SeText" syntax:
Header 1
========
Header 2
--------
Header 1
Header 2
The "atx" syntax can create headers of any level by changing the number of hash (#):
# Header 1 #
## Header 2 ##
###### Header at level 6
Header 1
Header 2
Header at level 6
Note that the tailing hashes are optional.
