[Plugin: Core Sidebars] Help, please!

I thought the whole point of using a plugin was to make things easier. I’m trying to put a unique sidebar on my “about” page, and I’d like to have the ability to have different sidebars for each page… but your instructions do not explain HOW to do that.

I have no idea where/how to add the code to customize each sidebar.

Please help!

thanks
