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).

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

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.

A horizontal dividing line: this is above it

and this is below it.

• Mainly useful for separating threads on Talk pages, please use sparingly on other pages.

Article about Thwarting Spambots.

• A link to another wiki 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:/wiki/Thwarting_Spambots, which is the page with the name "Thwarting Spambots".

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).

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.

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

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

• 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 . _ \ / ~ % - + & # ? ! = ( ) @ \x80-\xFF
• If a URL contains a character not in this list, it should be encoded by using a percent sign (%) followed by the hex code of the character, which can be found in the table of ASCII printable characters. For example, the caret character (^) would be encoded in a URL as %5E.

The image rotation system uses thumbnails from the photo gallery. Within the <imgarray></imgarray> tags you may specify the directory name of one album (as seen in the URL, not within the title of the pages).

By default a picture is floated to the right, with the top of the picture beginning where the tag was placed in the text, so it is generally a good idea to include the tag before the paragraph next to which you'd like it to appear.

If you don't place an album directory within the tag, you will get a random picture picked from amoung all of the albums in the gallery.

If you include this tag more than once on the page, you will get a different picture every time, even if you use the same album directory in them all. Pictures will not be selected from sub-albums.

If you place the word left within the tags, separated from the album name with a comma, the picture will be floated to the left instead of the right. Note also that if you place a directory name (from the gallery) and an image name from within that directory together, instead of a random image you will get the one specific image you have asked for.

By default a picture is floated to the right,

a good idea to include the tag ''before'' the
paragraph next to which you'd like it to appear.

<imgarray></imgarray>
If you don't place an album directory within the
tag, you will get a random picture picked from
amoung '''all''' of the albums in the gallery.

If you include this tag more than once on the
page, you will get a different picture every
time, even if you use the same album directory
in them all.  Pictures will not be selected from
sub-albums.

If you place the word '''left''' within the tags,
separated from the album name with a comma,

name from within that directory together, instead

You can strike out deleted material and underline new material.

You can also mark deleted material and inserted material using logical markup rather than visual markup.

• When editing regular Wikipedia articles, just make your changes and don't mark them up in any special way.
• When editing your own previous remarks in talk pages, it is sometimes appropriate to mark up deleted or inserted material.

You can <s>strike out deleted material</s>
and <u>underline new material</u>.

You can also mark <del>deleted material</del> and
<ins>inserted material</ins> using logical markup
rather than visual markup.
