How do you make infoboxes in MediaWiki?

I'm making a wiki using MediaWiki. I've seen a right side bar of each page on other wikis.

The right side bar has information about the thing that the wiki post explains or what ever.

Example screenshot of what I want:

https://minecraft.fandom.com/wiki/Diamond_Ore

I want to know if it's possible to make that on each page, and how?

Most Wikipedia Infoboxes are just tables, with a right side float and some additional style, colors, etc.

Minimal Infobox example

Here a minimal example floating table with 1 column (and 1 row):

{| style="float:right; border:1px solid black; width:270px"
| My fantastic infobox
|-
| More info
|}

To understand that syntax, read the official documentation:

https://www.mediawiki.org/wiki/Help:Tables

Example Infobox with Image

You may be surprised that, this infobox is just a table with two columns and some rows:

Here the code:

{| style="float:right; border:1px solid black; width:270px"
!colspan="2" | Fantastic Page
|-
!colspan="2" | [[File:Example image.svg|260px]]
|-
! Info
| Stuff
|-
! More Info
| More Stuff
|-
! And Info
| Again Stuff
|}

Useful extra information:

• if you know CSS, use CSS classes and use the extension TemplateStyle to create a dedicated page with your CSS rules
• if you want to create a parametrized template, read the page about MediaWiki template so that you do not need anymore to manually type that table in every page, but you just express some parameters.

Note: this is OK for the presentational side, but for the content side one should also carefully think where to store the actual data. Especially if you want to create a wiki farm. Possibilities include standard wikitext/template syntax, SemanticMediaWiki, Wikibase.
