Start your sections as follows:

New section

Subsection

Sub-subsection

• Start with a second-level heading (==); do not use first-level headings (=).
• Do not skip levels (e.g., second-level followed by fourth-level).
• A Table of Contents will automatically be added to an article that has four or more sections.

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 function diff (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).

and improves the function ''diff'' 
(used internally to compare

But an empty line
starts a new paragraph.

You can break lines
without starting a new paragraph.

• Please use this sparingly.
• Close markup between lines, don't start a link or italics or bold on one line and close it on the next.

You can break lines<br>
without starting a new paragraph.

• Lists are easy to do:
  • Start every line with a star.
    • More stars means deeper levels.
      • A newline in a list

marks the end of a list item.

• An empty line starts a new list.

* Lists are easy to do:
** Start every line with a star.
*** More stars means deeper levels.
**** A newline in a list
marks the end of a list item.

* An empty line starts a new list.

1. Numbered lists are also good
   1. very organized
   2. easy to follow
      1. easier still

• You can even do mixed lists
  1. and nest them

Definition list 

list of definitions

item 

the item's definition

another item

the other item's definition

• One item per line; a newline can appear before the colon, but using a space before the colon improves parsing.

; Definition list : list of definitions
; item : the item's definition
; another item
: the other item's definition

A colon indents a line or paragraph.

A manual newline starts a new paragraph.

• This is primarily for displayed material, but is also used for discussion on Talk pages.

IF a line starts with a space THEN
it will be formatted exactly
as typed;
in a fixed-width font;
lines won't wrap;
ENDIF

• This is useful for:
  • pasting preformatted text;
  • algorithm descriptions;
  • program source code;
  • ASCII art;
  • chemical structures;
• WARNING: If you make it wide, you force the whole page to be wide and hence less readable, especially for people who use lower resolutions. Never start ordinary lines with spaces.

• Note the American spelling of "center" (not "centre").

<center>Centered text.</center>

A horizontal dividing line: this is above it

and this is below it.

• Mainly useful for separating threads on Talk pages.
• Also used to disambiguate within an article without creating a separate page.

London has public transport.

• A link to another "internal" article.
• Internally, the first letter of the target page is automatically capitalized and spaces are represented as underscores (typing an underscore in the link has the same effect as typing a space, but is not recommended).
• Thus the link above is to the URL http://www.wikipedia.org/wiki/Public_transport, which is the Wikipedia article with the name "Public transport". See also Wikipedia:Canonicalization.

London has [[public transport]].

San Francisco also has public transportation.

• Same target, different name.
• This is a piped link.

San Francisco also has
[[public transport|public transportation]].

San Francisco also has public transportation.

Examples include buses, taxis and streetcars.

• Endings are blended into the link.
• Preferred style is to use this instead of a piped link, if possible.

San Francisco also has
[[public transport]]ation.

Examples include [[bus]]es, [[taxi]]s
and [[streetcar]]s.

See the Wikipedia:Manual of Style.

• A link to another namespace.

See the [[Wikipedia:Manual of Style]].

Economics#See also is a link to a section within another page.

#Links and URLs is a link to a section on the current page.

• The part after the number sign (#) must match a section heading on the page, or an identifier created in some other way. Matches must be exact in terms of spelling, case and punctuation. Links to non-existent sections aren't broken; they are treated as links to the top of the page.
• Identifiers may be created by attaching an id="..."> attribute to almost any HTML element.

[[Economics#See also]] is a link
to a section within another page.

[[#Links and URLs]] is a link
to a section on the current page.

[[#example]] is a link to an
anchor that was created using

Automatically hide stuff in parentheses: kingdom.

Automatically hide namespace: Village Pump.

Or both: Manual of Style

But not: [[Wikipedia:Manual of Style#Links|]]

• The server fills in the part after the pipe character (|) when you save the page. The next time you open the edit box you will see the expanded piped link. When previewing your edits, you will not see the expanded form until you press Save and Edit again. The same applies to links to sections within the same page (see previous entry).

Automatically hide stuff in parentheses:

The weather in London is a page that doesn't exist yet.

• You can create it by clicking on the link (but please don't do so with this particular link).
• To create a new page:
  1. Create a link to it on some other (related) page.
  2. Save that page.
  3. Click on the link you just made. The new page will open for editing.
• For more information, see How to start a page and check out Wikipedia's naming conventions.
• Please do not create a new article without linking to it from at least one other article.

[[The weather in London]] is a page 
that doesn't exist yet.

Wikipedia:How to edit a page is this page.

• Self links appear as bold text when the article is viewed.
• Do not use this technique to make the article name bold in the first paragraph; see the Manual of Style.

When adding a comment to a Talk page, you should sign it by adding three tildes to add your user name:

Ben Brockert

or four to add user name plus date/time:

Ben Brockert 00:18, Nov 19, 2004 (UTC)

Five tildes gives the date/time alone:

00:18, Nov 19, 2004 (UTC)

• The first two both provide a link to your user page.

When adding a comment to a Talk page,
you should sign it by adding

• Redirect one article title to another by placing a directive like the one shown to the right on the first line of the article (such as at a page titled "USA").
• Note that, while it is possible to link to a section, it is not possible to redirect to a section. For example, "#REDIRECT [[United States#History]]" will redirect to the United States page, but not to any particular section on it. This feature will not be implemented in the future, so such redirects should not be used.

#REDIRECT [[United States]]

• To put an article in a Wikipedia:Category, place a link like the one to the right anywhere in the article. As with interlanguage links, it does not matter where you put these links while editing as they will always show up in the same place when you save the page, but placement at the end of the edit box is recommended.

[[Category:Character sets]]

• To link to a Wikipedia:Category page without putting the article into the category, use an initial colon (:) in the link.

Three ways to link to external (non-wiki) sources:

1. Bare URL: http://www.nupedia.com/ (bad style)
2. Unnamed link: [1] (bad style)
3. Named link: Nupedia

See MetaWikiPedia:Interwiki_map for the list of shortcuts.

• Square brackets indicate an external link. Note the use of a space (not a pipe) to separate the URL from the link text in the "named" version.
• In the URL, all symbols must be among:
  A-Z a-z 0-9 . _ \ / ~ % -
