This Editing Overview has a lot of wikitext examples. You may want to keep this page open in a browser window for reference while you edit.
Each of the topics covered here is covered somewhere else in more detail. Please look in the box on the right for the topic you are interested in.
Editing basics
- Start editing
- To start editing a MediaWiki page, click on the "Edit this page" (or just "edit") link at one of its edges. This will bring you to the edit page: a page with a text box containing the wikitext: the editable source code from which the server produces the webpage. If you just want to experiment, please do so in the , not here.
- Summarize your changes
- You should write a short edit summary in the small field below the edit-box. You may use shorthand to describe your changes, as described in the .
- Preview before saving
- When you have finished, press preview to see how your changes will look -- before you make them permanent. Repeat the edit/preview process until you are satisfied, then click "Save" and your changes will be immediately applied to the article.
Wikitext markup — making your page look the way you want
- You can see some more detailed examples at Help:Wiki markup examples.
- If you want to try out things without danger of doing any harm, you can do so in the .
Basic text formatting
| What it looks like |
What you type |
|
You can emphasize text by putting two apostrophes on each side. Three apostrophes will emphasize it strongly. Five apostrophes is even stronger.

A single newline has no effect on the layout.
But an empty line starts a new paragraph.

You should "sign" your comments on talk pages:
- Three tildes gives your user name: Karl Wick
- Four tildes give your user name plus date/time: Karl Wick 07:46, 27 November 2005 (UTC)
- Five tildes gives the date/time alone: 07:46, 27 November 2005 (UTC)

You can use HTML tags, too, if you want. Some useful ways to use HTML:
Put text in a typewriter font. The same font is generally used for computer code.
Strike out or underline text, or write it in small caps.
Superscripts and subscripts: x2, x2
Invisible comments that only appear while editing the page. Comments should usually go on the talk page, though.

You can use <b>HTML tags</b>, too, if you
want. Some useful ways to use HTML:
Put text in a <tt>typewriter font</tt>.
The same font is generally used for
<code>computer code</code>.
<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:
x<sup>2</sup>, x<sub>2</sub>
Invisible comments that only appear while editing the page.
<!-- Note to editors: blah blah blah. -->
Comments should usually go on the talk page, though.

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.
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 two equals signs; don't use single equals signs.

- Unordered lists are easy to do:
- Start every line with a star.
- More stars indicate a deeper level.
- A newline
- in a list
marks the end of the list.
- Of course you can start again.

** Start every line with a star.
*** More stars indicate a deeper level.
* A newline

- Numbered lists are also good:
- Very organized
- Easy to follow
A newline marks the end of the list.
- New numbering starts with 1.

Another kind of list is a definition list:
- word
- definition of the word
- longer phrase
- phrase defined
|
Another kind of list is a '''definition list''':
; word : definition of the word
; longer phrase
: phrase defined

- A colon indents a line or paragraph.
A newline after that starts a new paragraph.

- This is often used for discussion on Talk pages.

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.

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.
You can put formatting around a link. Example: Wikipedia.
The first letter will automatically be capitalized, so wikipedia is the same as Wikipedia. Capitalization matters after the first letter.
The weather in London is a page that doesn't exist yet. You can create it by clicking on the link.

Example: ''[[Wikipedia]]''.
The ''first letter'' will automatically be capitalized,
so [[wikipedia]] is the same as [[Wikipedia]].
Capitalization matters after the first letter.
[[The weather in London]] is a page that doesn't exist
yet. You can 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]].
*[[List of cities by country#Sealand]].
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.

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 redirect the user to another page with a special link. For example, you might want to redirect USA to United States.
|
#REDIRECT [[United States]]
|
|
Category links don't show up, but add the page to a category.
Add an extra colon to actually link to the category: Category:English documentation

Just show what I typed
A few different kinds of formatting will tell the Wiki to display things as you typed them.
|

What you type |
| <nowiki> tags |
The nowiki tag ignores [[Wiki]] ''markup''. It reformats text by removing newlines and multiple spaces. It still interprets special characters: →

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

stops the text from being reformatted. It still
interprets Wiki markup and special
characters: →

Templates
Templates are segments of Wiki markup that are meant to be copied automatically ("transcluded") into a page. You add them by putting the template's name in {{double braces}}.
Some templates take parameters, as well, which you separate with the pipe character.

Tips and tricks
Page protection
In a few cases, where an administrator has protected a page, the link labeled "Edit this page" is replaced by the text "View source" (or equivalents in the language of the project). In that case the page cannot be edited. Protection of an image page includes protection of the image itself.
Edit conflicts
If someone else makes an edit while you are making yours, the result is an edit conflict. Many conflicts can be automatically resolved by the Wiki. If it can't be resolved, however, you will need to resolve it yourself. The Wiki gives you two text boxes, where the top one is the other person's edit and the bottom one is your edit. Merge your edits into the top edit box, which is the only one that will be saved.
Reverting
The edit link of a page showing an old version leads to an edit page with the old wikitext. This is a useful way to restore the old version of a page. However, the edit link of a diff page gives the current wikitext, even if the diff page shows an old version below the table of differences.
Error messages
If you get an error message upon saving a page, you can't tell whether the actual save has failed or just the confirmation. You can go back and save again, and the second save will have no effect, or you can check history and/or "My contributions" to see whether the edit went through. However, when you are adding a new comment on a talk page, clicking the save button twice will add two identical sections, so you might want to check the history and/or "My contributions" first.
Checking spelling and editing in your favorite editor
You may find it more convenient to copy and paste the text first into your favorite text editor, edit and spell check it there, and then paste it back into your web browser to preview. This way, you can also keep a local backup copy of the pages you have edited. It also allows you to make changes offline.
If you edit this way, it's best to leave the editing page open after you copy from it, using the same edit box to submit your changes, so that the usual edit conflict mechanism can deal with it. If you return to the editing page later, please make sure that nobody else has edited the page in the meantime. If someone has, you'll need to merge their edits into yours by using the diff feature in the page history.
Composition of the edit page
The editing page consists of these sections:
- The edit toolbar (optional)
- The editing text box
- The edit summary box
- Save/Preview/Cancel links
- A list of templates used on the page
- A preview, if you have requested one. Your preferences may place the preview at the top of the page instead.
Position-independent wikitext
No matter where you put these things in the wikitext, the resulting page is displayed the same way:
Minor edits
A logged-in user can mark an edit as "minor". Minor edits are generally spelling corrections, formatting, and minor rearrangement of text. Users may choose to hide minor edits when viewing Recent Changes.
Marking a significant change as a minor edit is considered bad Wikiquette. If you have accidentally marked an edit as minor, make a dummy edit, verify that the "[ ] This is a minor edit" check-box is unchecked, and explain in the edit summary that the previous edit was not minor.
