You can use wiki links to link pages together by simply using the page name surrounded by double square brackets. You create wiki links the same way whether you are linking to existing wiki pages or pages that do not exist yet.
For example, to quickly add a link from a wiki page back to the home page for your wiki, type [[Home]].
Here are some examples of links:
- [[Dogs]] : A link to a page named Dogs in the same folder.
[[Animals/Dogs]] : A link to a page named Dogs in a subfolder called Animals.
[[List:Announcements/Welcome]] : A link to the item called Welcome in the Announcements list on this site.
To display double opening or closing brackets without making a link, type a backslash before the two brackets. For example, [[ or ]].
