**Motivation**
The [[ https://www.mediawiki.org/wiki/Extension:Popups | extension manual for the pop up extension ]] currently only covers PagePreviews. We need to adapt it to include ReferencePreviews as well.
**Acceptance Criteria**
[] The [[ https://www.mediawiki.org/wiki/Extension:Popups | Popups extension manual ]] includes all relevant topics for ReferencePreviews as well.
[] The [[ https://www.mediawiki.org/wiki/Extension:Popups | Popups extension manual ]] contains a "Link" section ([[https://www.mediawiki.org/wiki/Extension:TwoColConflict#Links | like this one ]]). It includes these links:
[] Page Previews: [[https://www.mediawiki.org/wiki/Page_Previews|Help page]] and [[https://www.mediawiki.org/wiki/Talk:Page_Previews|central feedback page]] on mw.org
[] Reference Previews: [[https://www.mediawiki.org/wiki/Help:Reference_Previews| Help page]] and [[https://www.mediawiki.org/wiki/Help_talk:Reference_Previews|central feedback page]] on mw.org, [[https://meta.wikimedia.org/wiki/WMDE_Technical_Wishes/ReferencePreviews|main project page]] on Meta
**Note**
Please keep in mind that the extension manual is designed for users installing the extension
