Wikipedia:Article Layout Template

This is a dummy article to help you get started with creating pages in the wiki. The first paragraph is usually a short dictionary-style definition of the subject matter. The gives the reader a quick answer, which may be all they required, and reassures them that they have come to the right page.

First heading
The main headings in the article are second level headings, defined with two equals signs in the wikitext. You never need to use the top-level heading style, defined with one equals sign, as it is reserved for article titles. As with a scientific article, you have plenty of freedom about how to organize your content, but the reader may have some expectations about the order and style that you may want to take into account.

Start with a brief bit of background about the subject. Relate it to other topics, using plenty of links. Create links with a pair of square brackets around key technical words and phrases.

Second heading
You can add as many sections as you think you need to 'spiral out' from the core of the topic. Use judgment to decide when to split out a separate article.

Subheading
In longer articles, it may make sense to have another level of headings. There are not many occasions when you will need to use H4 headings (four = signs), so don't go there unless it's unavoidable. Never use more than four.
