Short description and usage of term
Internal links are created by using square brackets. You can either just give a pagename or use an additional link text.
DokuWiki supports multiple ways of creating links. External links are recognized automagically: http://www.google.com or simply www.google.com - You can set link text as well: This Link points to google. Email addresses like this one: email@example.com are recognized, too.
