You might want to learn simply how to start a page, and you might want informal tips on contributing to Wikipedia. If you want the details about how to edit a Wikipedia page, though, you've come to the right place.

It's very easy to edit a Wiki page. Simply click on the "edit this page right now!" link at the top or bottom of a Wiki page. This will bring you to a page with a text box containing the text of that Wiki page.

Then type away, and press "Save" when finished! (You can also preview your changes before saving if you like.)

It is often more convenient to copy and paste the text first into your favorite text editor, edit and spell check there, and then paste back into the browser to preview. You can also keep a local copy of the pages you authored so that you can make changes offline.

In the left column of the table below, you can see what effects are possible. In the right column, you can see how those effects were achieved. In other words, to make text look like it looks in the left column, type it in the format you see in the right column.

You may want to keep this page open in a separate browser window for reference. If you want to try out things without danger of doing any harm, you can do so in the SandBox.


Sections, Paragraphs, Lists and Lines

Start your sections with header lines:

New Section

==== Subsection ====


=== New Section ===

==== Subsection ====

A single newline has no effect.

But an empty line

starts a new paragraph.

  • Lists are good:
    • they organize material
    • they look clean
* Lists are good:
** they organize material
** they look clean
  1. Numbered lists are also good
    1. Very organized
    2. easy to follow

Definition lists 
lists with definitions
item to be defined 
the item's definition
; Definition lists : lists with definitions
; item to be defined : the item's definition
For mixing list types, you need to use HTML:
  • A numbered list:
    1. First item
    2. Second item
  • more bullets
<ul>
<li>A numbered list:
<ol>
<li>First item
<li>Second item
</ol>
<li>more bullets
</ul>
Lines can be

IF (a line starts with whitespace) THEN
  it will be formatted exactly as typed;
  in a technical looking font;
  lines won't wrap;

this is useful for:
  • pasting preformatted text;
  • algorithm descriptions;
• ascii art;

Character formatting

Emphasize, strongly, very strongly.
Use also in formulas: F = m a.
''Emphasize'', '''strongly''', '''''very strongly'''''.
  '''F''' = ''m'' '''a'''.
Funny fonts

But == ... == is better for

separating sections.
<font size=+2 color=red>Funny fonts</font>
A typewriter font for technical terms.
<tt>technical terms</tt>
You can strike out stuff
and insert new stuff. Useful for editing.
You can <strike>strike out</strike> stuff
and <u>insert new stuff</u>

If your table doesn't look right, make sure that all and and tags. It's best to start all lines belonging to a table in the first column as in the example above, or else you will get spurious space above the table.
