From LinuxMCE wiki
You can look at "edit" of this page to see how the following simple markup works:
Second: This is how you can do a section header
Third: Which can be nested by adding more equal signs
The headings will be put into a table of contents at the top, but only when the page has 4 or more section headers (nested or not).
- This is an unordered (bullet) list.
- These can also be nested
- This is an ordered (numbered) list
- I think these can be nested as well
- They can
- Next ordered (numbered) list
- This will be indented
- Indented more
Lines starting with a space will be "preformatted", and placed in one of those typical dotted boxes.
italic and bold
URLs are automaticly recognized, but there are more possibilities. For example: http://some.domain/page.html shows the URL 'as is'  shows up as an increasing number alternative text shows up as "alternative text"
this will stop the wiki from applying formatting; useful if you don't want URLs turned into links, for instance: http://some.domain/page.html
Alternatively, you can use the standard HTML tags.
Third Level: You unnest by removing one level of equal signs
Instead of deleting sentence of a paragraph of text, instead first use <del> and </del>:
So that text stays visible at first until some of the senior admins decides what to do with that text.
You can color a text by placing it between <span style="color:Red;"> </span> tags. In this example, the color is red. Below is a list containing other colors you can use. Simply copy a line, and type the text you want to color between the ">" and the "</span>".
