Thread:Project:Support desk/How to install infobox in latest mediawiki

Hi there, Can you give me a simple installation procedure for infobox. I am searching for infobox installation in latest mediawiki for about two days. I have googled it and didnt find any useful tutorials about that. Whether in default mediawiki,infobox is deactivated or not. I have gone through this tutorial http://www.etcwiki.org/wiki/Install_infobox but having a considerable difficult understanding the installation procedure.

What is commmon.css? i didn't any in my mediawiki

I tried to add this code in my mediawiki

but getting this Template:infobox in red link but when i tried sandbox its working fine

Please provide some easy installation tutorial for infobox. I think i am not alone in this while googling i found most of the people have same problem as like me most are not very good in programming.
