General

To edit a MediaWiki page, click on the "Edit" tab above or on a section "edit" link on the right. This will bring you to the edit page: a page with a text box containing the editable text. Depending on the preferences that have been set, a version of the edit page called preview page appears: in this case the rendered page is also shown; if not you get it by pressing "Show preview" (see below).

After adding to or changing the wikitext it is useful to press "Show preview", which produces the corresponding webpage in your browser but does not make it publicly available yet (not until you press "Save page"). Errors in formatting, links, tables, etc., are often much easier to discover from the rendered page than from the raw wikitext.



Composition of the edit page

  • Edit Toolbar (optional)
  • Edit Box
  • Edit Summary box
  • Save/Preview/Cancel links
  • List of templates used
  • Preview (optionally either on every edit page or just after pressing "Show preview"; optionally the first item)



Minor edits

When editing a page, a user has the option of flagging the edit as a "minor edit". This feature is important, because users can choose to hide minor edits in their view of the Recent Changes page to keep the volume of edits down to a manageable level.

When to use this is somewhat a matter of personal preference. The rule of thumb is that an edit of a page that consists of spelling corrections, formatting, and minor rearranging of text should be flagged as a "minor edit". A major edit is basically something that makes the entry worth revisiting for somebody who wants to watch the article rather closely. So any "real" change, even if it is a single word, should be flagged as a "major edit".


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).

When used in a list, a newline ''does''

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.

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: George Barouxis
- Four tildes give your signature plus date/time: George Barouxis 07:46, 27 November 2005 (UTC)
- Five tildes gives the date/time alone: 07:46, 27 November 2005 (UTC)

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.


What it looks like What you type

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
Centered text
  • Please note the American spelling of "center".
<center>Centered text</center>

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.

  • 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 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.

    2. inside each other
      • or break lines
        in lists.

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.

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.[1]

Links

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

What it looks like What you type

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.

The ''first letter'' of articles is automatically

first letter.

The weather in Moscow is a page that doesn't exist yet. You could create it by clicking on the link.

[[The weather in Moscow]] 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:

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. [[#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.

Or you can use the "pipe trick" so that text in parentheses or text after a comma does not appear.


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

*[[Spinning (textiles)|]]
*[[Boston, Massachusetts|]]

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]

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

You can give it a title:
[http://www.nupedia.com Nupedia]

Or leave the title blank:

Linking to an e-mail address works the same way: mailto:someone@domain.com or someone

Linking to an e-mail address works the same way:
mailto:someone@domain.com or 
[mailto:someone@domain.com someone]

You can redirect the user to another page.

#REDIRECT [[Official position]]

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

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

[[Help:Category|Category links]] do not show up in line
but instead at page bottom ''and cause the page to be

Just show what I typed

See also Text formatting examples.

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

What it looks like What you type

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''.
It reformats text by 
removing
newlines    and multiple
 spaces.
It still interprets special
characters: &rarr;
</nowiki>
The pre tag ignores [[Wiki]]
 ''markup''.
It also doesn't     reformat
 text.
It still interprets special
characters: →
<pre>
The pre tag ignores [[Wiki]]
 ''markup''.
It also doesn't     reformat
 text.
It still interprets special
characters: &rarr;
</pre>

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: →

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 syntax for uploading a file [[Image:filename.png]]

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

Mathematical formulas

The site has MathML support through ASCIIMathML, a javascript based system that translates "ASCII" notation (the one often used in newsgroups and emails) placed in \` delimiters to MathML. La-TeX-style formulas also work. So registered users can use this notation in any page of the site for rendering mathematical formulas.

For Detailed Syntax see Help:Formula.

What it looks like What you type

`x_(1,2)=(-b+-sqrt(b^2-4ac))/(2a)`
