[[File:Boldness and links tutorial.ogv|thumb||thumbtime=1|A video tutorial about the basics of wiki markup, including creating links]]
'''Wikilinks''' are one of the ''key'' components of Wikipedia. A [[help:wikilink|wikilink]] connects to another page on the encyclopaedia and ties the whole thing together.
In general, wikilinks should be added for the [[MOS:LINK|first occurrence]] of important concepts for the topic.
All Wikilinks are based on using square brackets like: <code><nowiki>[[target page]]</nowiki></code>.
If you want to link to an article, but display some other text for the link, you can use a [[Help:Link#Piped link|pipe]] <code><nowiki>|</nowiki></code> divider ({{key press|Shift|\}}):
:<code><nowiki>[[link]]</nowiki></code> displays as [[link]]
:<code><nowiki>[[Android (operating system)|Android]]</nowiki></code> displays as [[Android (operating system)|Android]]
:<code><nowiki>[[Wikipedia:Tutorial/Wikipedia_links#Categories|Categories]]</nowiki></code> displays as [[Wikipedia:Tutorial/Wikipedia_links#Categories|Categories]]
