Where can I get templates for MediaWiki?

Question

I have noticed that a lot of mediawiki-based websites use such templates as Robelbox, Ambox etc. Where can I get them and how should they be installed?

Answer 1

This task is a bit more involved than just exporting and importing.

A "simple" overview can be found here -> How to add Wikipedia templates to your own Mediawiki

• Upgrade our MediaWiki to the latest stable version, hoping to match Wikipedia’s one.

• Install the Scribunto extension and properly configure it.

• Export/Import the LUA modules used by the (meta)templates you want to use and import them in your MediaWiki.

• Export/Import the Wikipedia templates you want to use, together with all the required metatemplates, and import them in your
  MediaWiki.

• Copy the relevant CSS classes from the Wikipedia’s Common.css file and paste them in your MediaWiki’s Common.css.

• Activate MediaWiki IstantCommons feature to automatically fetch the Template image files from the commons.wikipedia.com repository.
