Need help with Schematic Setup

I am trying to setup Creo Schematics for my design company and I am having some major issues;

1. How do I create a central catalog

2. How do I populate a central catalog with a downloaded library.

3. How do I make myself an admin and would this help with the previous two problems

Any help would be greatly appreciated but DO NOT just send me a link to PTC help center because it does not contain instructions.
