Hi neostar,
This descibes the normal process of adding a componenet to Joomla. What you do is:
1. Download the componenet you want from the supplier's site.
2. Open your Site's Joomla admin area.
3. On the top menu - Extensions / install, browse to the location of the zip file containing the component.
4. Click install.
5. Wait and you should get a message saying the uinstall has been successful.
6. Find the new componenet listed on the "components" menu in the admin back end.
That's about it, and that's how you instal CB, and everything else you might wat to add to Joomla.
Good luck,
Pete
