The Documentation Link macro generates a customisable text link to a page on http://confluence.atlassian.com/.

This macro accepts a relative link value and automatically prefixes that value with the URL:

http://confluence.atlassian.com/

For example, if you use the following relative link:

display/DOC/Working+with+Macros

then the resulting URL is:

http://confluence.atlassian.com/display/DOC/Working+with+Macros

The text that will be hyperlinked is the macro's body text (that is, the text between the macro tags). See the example below.
