This Editing Overview has a lot of wikitext examples. You may want to keep this page open in a separate browser window for reference while you edit. Each of the topics covered here is covered somewhere else in more detail. See box at right for that

## Editing basics

Start editing
To start editing a MediaWiki page, click the Edit this page (or just edit) link at one of its edges. This brings you to the edit page: a page with a text box containing the wikitext: the editable source code from which the server produces the webpage. If you just want to experiment, please do so in the sandbox, not here.
Type your changes
You can just type your text. However, also using basic wiki markup (described in the next section) to make links and do simple formatting adds to the value of your contribution.
Summarize your changes
Write a short edit summary in the small field below the edit-box. You may use shorthand to describe your changes, as described in the legend.
Preview before saving
When you have finished, click Show preview to see how your changes will look -- before you make them permanent. Repeat the edit/preview process until you are satisfied, then click Save page and your changes will be immediately applied to the article.

### Basic text formatting

What it looks like What you type

You can italicize text by putting 2 apostrophes on each side.

3 apostrophes will bold the text.

5 apostrophes will bold and italicise the text.

(4 apostrophes don't do anything special -- there's just 'one left over'.)

You can ''italicize text'' by putting 2
apostrophes on each side.

3 apostrophes will bold '''the text'''.

5 apostrophes will bold and italicize
'''''the text'''''.

(4 apostrophes don't do anything special -- there's just ''''one left over''''.)


A single newline has no effect on the layout. But an empty line

starts a new paragraph.

You can break lines
without a new paragraph.
Please use this sparingly.

You should "sign" your comments on talk pages:
- Three tildes gives your user name: Karl Wick
- Four tildes give your user name plus date/time: Karl Wick 07:46, 27 November 2005 (UTC)
- Five tildes gives the date/time alone: 07:46, 27 November 2005 (UTC)

You should "sign" your comments
on talk pages: <br />
- Three tildes gives your user
name: ~~~ <br />
- Four tildes give your user
name plus date/time: ~~~~ <br />
- Five tildes gives the
date/time alone: ~~~~~ <br />


You can use HTML tags, too, if you want. Some useful ways to use HTML:

Put text in a typewriter font. The same font is generally used for computer code.

Strike out or underlinetext, or write it in small caps.

Superscripts and subscripts: X2, H2O

Invisible comments to editors (<!-- -->) only appear while editing the page.

If you wish to make comments to the public, you should usually go on the talk page, though.

You can use <b>HTML tags</b>,
too, if you want. Some useful
ways to use HTML:

Put text in a <tt>typewriter
font</tt>. The same font is
generally used for <code>
computer code</code>.

<strike>Strike out</strike>
or <u>underline</u> text,
or write it <span style=
"font-variant:small-caps">
in small caps</span>.

Superscripts and subscripts:
X<sup>2</sup>, H<sub>2</sub>O

Invisible comments to editors (&lt;!-- --&gt;)
only appear while editing the page.
<!-- Note to editors: blah blah blah. -->

If you wish to make comments to the public,
you should usually go on the [[talk page]], though.


For a list of HTML tags that are allowed, see HTML in wikitext. However, you should avoid HTML in favor of Wiki markup whenever possible.

### Organizing your writing

What it looks like What you type
Section headings

Headings organize your writing into sections. The Wiki software can automatically generate a table of contents from them.

Subsection

Using more equals signs creates a subsection.

A smaller subsection

Don't skip levels, like from two to four equals signs.

Start with 2 equals signs not 1 because 1 creates H1 tags which should be reserved for page title.

• Unordered lists are easy to do:
• Start every line with a star.
• More stars indicate a deeper level.
Previous item continues.
• A new line
• in a list

marks the end of the list.

• Of course you can start again.

1. Numbered lists are:
1. Very organized
2. Easy to follow

A new line marks the end of the list.

1. New numbering starts with 1.

Another kind of list is a definition list:

Word
Definition of the word
Here is a longer phrase that needs a definition
Phrase defined
A word
Which has a definition
Also a second one
And even a third
Another kind of list is a ''definition list'':
; Word : Definition of the word
; Here is a longer phrase that needs a definition
: Phrase defined
; A word : Which has a definition
: Also a second one
: And even a third

• You can even do mixed lists
1. and nest them
2. inside each other
• or break lines
in lists.
definition lists
can be
nested too
* You can even do mixed lists

*# inside each other

A colon (:) indents a line or paragraph.

A new line after that starts a new paragraph.
This is often used for discussion on talk pages.

We use 1 colon to indent once.
We use 2 colons to indent twice.
We use 3 colons to indent 3 times, and so on.

You can make horizontal dividing lines (----) to separate text.

But you should usually use sections instead, so that they go in the table of contents.

You can add footnotes to sentences using the ref tag -- this is especially good for citing a source.

There are over six billion people in the world.[1]
