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

3 apostrophes will embolden the text.

5 apostrophes will embolden and italicize the text.

(Using 4 apostrophes doesn't do anything special --
the last pair 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 '''embolden the text'''. 

5 apostrophes will '''embolden''' and ''italicize'' 
'''''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).

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

Please do not start a link or italics or bold text on one line and end on the next.

• Three tildes gives your signature: Example
  
• Four tildes give your signature plus date/time: Example 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:
- Three tildes gives your
signature: ~~~

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

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 newline
• 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 newline marks the end of the list.

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 definition

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.

; Word : Definition of the word

     • or break lines
       in lists.

A colon (:) indents a line or paragraph.

A newline starts a new paragraph.
Should only be used on talk pages.
For articles, you probably want the blockquote tag.

We use 1 colon to indent once.

We use 2 colons to indent twice.

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.

You can put formatting around a link. Example: Wikipedia.

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.

Intentionally permanent red link is a page that doesn't exist yet. You could create it by clicking on the link.

[[Intentionally permanent red link]] is a page that doesn't exist
yet. You could create it by clicking on the link.

You can link to a page section by its title:

• Doxygen#Doxygen Examples..

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:

* [[Doxygen#Doxygen Examples]].

If multiple sections have the same title, add
a number. [[#Example section 3]] goes to the
third section named "Example section".

You can make a link point to a different place with a piped link. Put the link target first, then the pipe character "|", then the link text.

• About Links
• Cities in Morocco

Or you can use the "pipe trick" so that a title that contains disambiguation text will appear with more concise link text.

• Spinning
• Boston

You can make a link point to a different place
with a [[Help:Piped link|piped link]]. Put the link
target first, then the pipe character "|", then
the link text.

* [[Help:Link|About Links]]
* [[List of cities by country#Morocco|Cities in Morocco]]

Or you can use the "pipe trick" so that a title that
contains disambiguation text will appear with more concise
link text.

You can make an external link just by typing a URL: http://www.nupedia.com

You can give it a title: Nupedia

Or leave the title blank: [1]

Category links do not show up in line but instead at page bottom and cause the page to be listed in the category.

Add an extra colon to link to a category in line without causing the page to be listed in the category: Category:English documentation

The Wiki reformats linked dates to match the reader's date preferences. These three dates will show up the same if you choose a format in your Preferences:

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

<nowiki>

It reformats text by 
removing

 spaces.

The pre tag ignores [[Wiki]]
 ''markup''.
It also doesn't     reformat
 text.
It still interprets special

Leading spaces are another way to preserve formatting.

Putting a space at the
beginning of each
line stops the text   
from being
reformatted.  It still 
interprets Wiki
markup and special
characters: →
