There isn't much formal documentation - wiki's aren't really about formal. In our company most people felt more comfortable with more documentation in the wiki than the QuickStart page that Ben provides.
We made a TextFormattingRules page, which is exactly the same as the "style tips" that appear when you are editing a page:
These rules are used to convert WikiMarkup into HyperTextMarkupLanguage.
==heading== creates a heading
===heading=== creates a sub-heading
—- creates a horizontal rule
~italic~ makes text italic
bold# makes text bold
Starting a line with a blank space makes it monospaced
Starting a line with a '*' creates a simple bullet list. Surround with list tags to indent.
Starting a line with ':' indents the entire paragraph. More ':'s increase the indent level.
You can create a table by preceding each cell value with a pipe: |
New rows are started by typing on a new line
Column headers are defined by using a double pipe: ||
[[your wiki page name]] is used for a wiki page link
A CamelCase word automatically also becomes a wiki page link
[http://example.com linkname] is used for external URL links
[file:filename linkname] is used to link to a file attached to this page
[notes://ServerName/filepath] creates a link that uses a Lotus Notes client.
[wiki:WikiWord alternate text] is used to link to a wiki page with alternate text
[image:filename] is used to display a graphic file attached to this page
[image:filename left] aligns an image left, [image:filename right] aligns it right
To prevent wiki formatting, put text inside a < nowiki > block
Allowed HTML is: < code >,< pre >,< blockquote >,< center >,< s >,< sup >,< cite >,< q >,< b >,< i >,< del >,< em >,< ul >,< ol >,< li >
Other things we ended up doing to ease introduction:
- A FrequentlyAskedQuestions page
- A StyleGuide page
- An ExampleMarkup Page
4. Adding links to articles in other wiki's such as http://www.benpoole.com/wiki and http://c2.com/cgi/wiki
