Editing an Existing Article vs. Creating a New Article

Existing articles can be edited, or new articles created.

Content Basics

The default WikiMedia engine is designed to display content in a left-to-right, top-to-bottom fashion. At the top of the article is the title, followed by a table of contents--if there are four or more headings--and the body copy. By default images are displayed on the right.

Headings and Subheadings

Articles with four or more headings automatically render a table of contents with headings listed. The code on the right overlay displays the results shown with arrows on the left.

Headings and subheading are used to break up content into navigable pieces.


To define a heading, bracket the word or phrase with two equal signs.

For example, if you type:
== Introduction ==
a main heading titled "Introduction" is created. This main heading is entered into the table of contents and divides the content from the heading with a hard return.


A subheading displays a smaller heading in large, bold format. A subheading is created by using three equal signs to bracket the word or phrase.

For example, if you type:
=== Beginning ===
a subheading titled "Beginning" is created.

More information about headings can be found at Wikipedia - Formatting
