Wikipedia is a WikiWiki, which means that anyone can easily edit any unprotected article and have those changes posted immediately to that page.
It's very easy to edit a Wiki page!!!
Simply click on the "Edit this page" tab at the top (or the edit link on the right or bottom) of a Wiki page. This will bring you to a page with a text box containing the editable text of that page. (If you want to experiment, please do so in our sandbox, not here. You could open the sandbox in a separate window or tab to be able to see both this text and your tests in the sandbox.)
Type away, write a short edit summary on the small field below the edit-box. You may use shorthand to describe your changes, as described in the legend, and when finished, press preview to see how your changes will look. Then press "Save". Depending on your system, pressing "Enter" while the edit box is not active (when there is no typing cursor in it) may have the same effect as pressing the "Save" button. Also, please do not vandalise the information on Wikipedia.
You can also click on the "Discussion" tab (or the "Discuss this page" link) to see the corresponding talk page, which contains comments about the page from other Wikipedia users. Click on the "+" tab (or "Edit this page") to add a comment.

Tips on editing Wikipedia articles
Please use a neutral point of view, and please cite your sources so others can check and extend your work.
It is often more convenient to copy and paste the text first into your favorite text editor, edit and spell check there, and then paste back into the browser to preview. This way, you can also keep a local backup copy of the pages you authored so that you can make changes offline. Some text editors can be specially adapted to edit Wikipedia articles: see Wikipedia:syntax highlighting.
If during editing you want to see the current version again, open "Cancel" in a new window. This does not cancel your edit.
After making a new page, it's a good idea to
- With your page displayed, use What links here to check the articles that already link to it, and make sure that they are all expecting the same meaning that you have supplied;
- Use the Search button to launch a Google search of Wikipedia for your topic title (and possibly variants), to find articles that mention it, and make links from them if appropriate;
- Check for corresponding articles in the Wikipedias of other languages that you can read.
Safari browser 60-second timeout
If you use the Safari browser on Mac OS X, you may find that the 60-second browser timeout is shorter than the amount of time it takes for your edit to be acknowledged, especially when server load is high. Clicking "Save page" again will cause the edit to be repeated, which can be disastrous when doing section edits. You may want to install SafariNoTimeout, a free extension that will increase the 60-second timeout to 10 minutes. Note that this "haxie" does not require Application Enhancer. Alternatively, the Safari plug-in Saft also allows you to alter the timeout, although it is not free.
Minor edits
See also Wikipedia:Minor edit
When editing a page, a logged-in user can mark that edit as "minor". Minor edits generally mean spelling corrections, formatting, and minor rearranging of text. It is possible to hide minor edits when viewing Wikipedia:Recent Changes. Marking a significant change as a minor edit is considered bad behavior, and even more so if it involves the deletion of some text. If one has accidentally marked an edit as minor, the person should edit the source once more, mark it major (or, rather, ensure that the check-box for "This is a minor edit" is not checked), and, in the summary, state that the previous change was a major one.
The wiki markup
In the left column of the table below, you can see what effects are possible. In the right column, you can see how those effects were achieved. In other words, to make text look like it looks in the left column, type it in the format you see in the right column.
You may want to keep this page open in a separate browser window for reference. If you want to try out things without danger of doing any harm, you can do so in the Sandbox.
Sections, paragraphs, lists and lines

Start your sections as follows:

A single newline generally has no effect on the layout. These can be used to separate sentences within a paragraph. Some editors find that this aids editing and improves the diff function (used internally to compare different versions of a page). But an empty line starts a new paragraph.

Tables
Placement of the Table of Contents (TOC)
At the current status of the wiki markup language, having at least four headers on a page triggers the TOC to appear in front of the first header (or after introductory sections). Putting __TOC__ anywhere forces the TOC to appear at that point (instead of just before the first header). Putting __NOTOC__ anywhere forces the TOC to disappear. See also compact TOC for alphabet and year headings.
Tables
There are two ways to build tables:
- in special Wiki-markup (see m:Help:Table)
- with the usual HTML elements: <table>, <tr>, <td> or <th>.
For the latter, and a discussion on when tables are appropriate, see Wikipedia:How to use tables.

NUMBEROFARTICLES is the number of pages in the main namespace which contain a link and are not a redirect, i.e. number of articles, stubs containing a link, and disambiguation pages).
Templates
The MediaWiki software used by Wikipedia has limited support for template inclusion. This means standardized text chunks (such as boilerplate text) can be inserted into articles. For example, typing {{stub}} will appear as This article is a stub. You can help Wikipedia by expanding it. when the page is saved. Other commonly used ones are {{disambig}} for disambiguation pages and {{spoiler}} for spoiler warnings. See Wikipedia:Template messages for the complete list.
