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 italicize the text. (Using 4 apostrophes doesn't do anything special -- there are just ' left over ones' that are included as part of the text.)	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'''''. (Using 4 apostrophes doesn't do anything special -- <br> there are just '''' left over ones'''' that are included as part of the text.)
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. When used in a list, a newline does affect the layout (see below).	A single [[w: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. When used in a list, a newline ''does'' affect the layout ([[#lists|see below]]).
You can break lines without a new paragraph. Please use this sparingly. Please do not start a link or italics or bold on one line and close it on the next.

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

HTML tags

You can use some HTML tags too. 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.

Put text in a typewriter font. The same font is generally used for computer code.	Put text in a <tt>typewriter font</tt>. The same font is generally used for <code> computer code</code>.
Strike out or underline text, or write it in small caps.	<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: X2, H2O	Superscripts and subscripts: X<sup>2</sup>, H<sub>2</sub>O

The blockquote command will indent both margins when needed instead of the left margin only as the colon does.	<blockquote> The '''blockquote''' command will indent both margins when needed instead of the left margin only as the colon does. </blockquote>
Invisible comments to editors (<!-- -->) only appear while editing the page. If you wish to make comments to the public, you should usually use the talk page.	Invisible comments to editors (&lt;!-- --&gt;) only appear while editing the page. <!-- Note to editors: blah blah blah. -->

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.	== Section headings == ''Headings'' organize your writing into sections.

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 newline in a list marks the end of the list. Of course you can start again.	* ''Unordered lists'' are easy to do: ** Start every line with a star. *** More stars indicate a deeper level. *: Previous item continues. ** A newline * in a list marks the end of the list. * Of course you can start again.
Numbered lists are: Very organized Easy to follow A newline marks the end of the list. New numbering starts with 1.	# ''Numbered lists'' are: ## Very organized ## Easy to follow A newline marks the end of the list. # New numbering starts with 1.
Here's a definition list: Word Definition of the word A longer phrase needing definition Phrase defined A word Which has a definition Also a second one And even a third Begin with a semicolon. One item per line; a newline can appear before the colon, but using a space before the colon improves parsing.

You can even do mixed lists and nest them inside each other or break lines in lists. definition lists can be nested too	* You can even do mixed lists *# and nest them *# inside each other *#* or break lines<br>in lists. *#; definition lists *#: can be *#:; nested : too
A colon (:) indents a line or paragraph. A newline starts a new paragraph. Often used for discussion on talk pages. We use 1 colon to indent once. We use 2 colons to indent twice. 3 colons to indent 3 times, and so on.	: A colon (:) indents a line or paragraph.

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.

Links

You will often want to make clickable links to other pages.

Here's a link to a page named Official position. You can even say Official positions and the link will show up correctly.	Here's a link to a page named [[Official position]]. You can even say [[Official position]]s and the link will show up correctly.
You can put formatting around a link. Example: Wikipedia.	You can put formatting around a link. Example: ''[[Wikipedia]]''.
The first letter of articles is automatically capitalized, so wikipedia goes to the same place as Wikipedia. Capitalization matters after the first letter.

You can link to a page section by its title: List of cities by country#Morocco. If multiple sections have the same title, add a number. #Example section 3 goes to the third section named "Example section".	You can link to a page section by its title: *[[List of cities by country#Morocco]]. If multiple sections have the same title, add a number.

Just show what I typed

See also Help:Wiki markup examples#Just show what I typed.

A few different kinds of formatting will tell the Wiki to display things as you typed them.

The nowiki tag ignores [[Wiki]] ''markup''. It reformats text by removing newlines and multiple spaces. It still interprets special characters: →	<nowiki> The nowiki tag ignores [[Wiki]] ''markup''.

Images, tables, video, and sounds

After uploading, just enter the filename, highlight it and press the "embedded image"-button of the edit_toolbar.

This will produce the sytax for uploading a file [[Image:filename.png]]

This is a very quick introduction. For more information, see:

• Help:Images and other uploaded files for how to upload files
• w:en:Wikipedia:Extended image syntax for how to arrange images on the page
• Help:Table for how to create a table

Templates

Templates are segments of Wiki markup that are meant to be copied automatically ("transcluded") into a page. You add them by putting the template's name in {{double braces}}.

Some templates take parameters, as well, which you separate with the pipe character.
