To divide an article into sections wiki uses headers as in the formulae below:
==Header== (2 equals signs on each side) produces:
===Subheader=== (3 equals signs on each side) produces:
====Sub-subheader==== (4 equals signs on each side) produces:
 Why to use headers
There are three reasons:
- The obvious, in that they act as little headlines.
- If there are three or more, they will be used automatically to make a table of contents.
- Each one creates a new "edit" link, allowing convenient editing of parts of an article.
Don't use one equals sign each side, try it and you'll see why.
Don't repeat a header's wording as another header, it causes a number of (trivial) problems.
You will note that all these sections have [ edit] links at the side. These links allow the section to be edited on its own apart from the rest of the article. To remove these links use __NOEDITSECTION__ (2 underscores each side) in the body after the header.
 That's all there is to it
That's all you need to know for starters.
Sections are actually quite complex and beyond the scope of this baby help page, if you want to get really confused read this.
