I am slightly embarrassed to ask this but I am a total web dev noob and after a lot of searching online I still can't figure out how to deploy the most basic template for a "Note" template as seen here. <https://www.mediawiki.org/wiki/Template:Note>
All the docs I can find talk about writing your own templates or exporting/importing them from other pages etc.
Is this actually required to get simple note box going like the examples on the above page (coloured box with simple icon)?
I would have thought this sort of basic stuff is included in the default installation but clearly I am missing something.
Any help would be appreciated.
