wiki : heading
Create headings (html <h2>, <h3>, <h4> and <h5> tags).
At the beginning of a line, sandwich the heading between a series of equal signs. The more equal signs, the lower level heading you will get.
Note, you cannot create a <h1> tag, as that is reserved for the page heading.
Example
To create the 'Example' heading above, I used this :
== Example ==
and for lower level headings, add more "=" symbols :
=== Sub Heading === ==== Smallest Heading ====
