The term "wikitext" refers to Wikipedia's wp:wiki markup language. Formats:

[[hyperlink]] or [[hyperlink|link here]] or [[expert]]ly → hyperlink or link here or expertly
[http://www.google.com external link] → external link (to an outside webpage)
[[File:Example.jpg|thumb|55px|Caption]] → (shows image, see below)
==Header== → Header ===Subheader=== → Subheader
''italic'' '''bold''' '''''bold-italic''''' → italic bold bold-italic
* bullet →  bullet (or ":*" or "::*" to indent)
Caption
: indent → indent (or "::" or "::::::" to indent more)
# numbered → 1. numbered ("#:" indents under numbered lines)
#* bullet under number → ° bullet under number
[[Category:xx]] → (internal wp:category link).
{{templt|aa|bb}} → (run "Template:Templt" with parameters "aa" & "bb")
{{#expr: (5*10 + 3^2 +8)/2 }} → calculate expression: (5×10 + 3²+8)/2 = 33.5
~~~~ → signature ~~~~~ → date/time (UTC)
