Tips for setting up your own MediaWiki

I just set up my first MediaWiki for our corporate intranet. It's easy to do, but the vanilla MediaWiki installation is missing some features that you'll probably want to duplicate from Wikipedia. I found myself wishing that there were some steps I could follow to get the wiki quickly to that point. Here's the result:

1. Install MediaWiki
2. Add the logo
3. Enable the 'upload files' capability
   
4. Copy the 'ambox' template from Wikipedia - also download a copy of all the little ambox icons
5. Install the Reference extension to enable actual footnotes
6. Install the FCKeditor MediaWiki extension
