Forum:Newb Help? Sorry to bother!

I'm really sorry to bother everyone on this wikia. I recently became the admin of a wikia, and I am trying to get the java code to work on it.

I'm starting completely from scratch, and have no idea what I'm doing. I am able to read and write a bit of java, but I'm just not understanding how you are supposed to create the initial setup.

I found a lot of guides on installing and setting up mediawiki on your own computer. Is it not something supported on the wikia directly? Do I need to do more than basic 'insert code here, hit go' ?

Specifically, I am trying to get things like the countdowns, sortable tables and collapsible data to work. No luck so far. Could anyone be bothered to show me an initial setup? Thank you so much!
