Wiki markup is a document encoding format that was first introduced by Cunningham’s WikiWikiWeb. Similarly to markdown, it consists of annotating a plain text file, but it fundamentally differs from it in that there are no wiki markup ‘flavors’—most wiki markup formats are incompatible with one another—and formatting annotations tend to be rather verbose, in comparison.

Each wiki markup format is typically associated with its respective, wiki engine:

• DokuWiki
• MediaWiki
• TWiki
• XWiki

DokuWiki

DokuWiki markup example:

===== This is a level 1 heading =====

==== This is a level 2 heading ====

This is text in **bold** and //italics//, and this is an external link to [[https://docops.guide|DocOps]]. Now, some bullet points:

* Bullet point 1
* Bullet point 2
* Bullet point 3

MediaWiki

MediaWiki markup example:
