How to remove joomla banner?

Question

Joomla

Hello!
Who understands in Joomla help, otherwise I'm generally down in it.
The bottom line: on the main page there is a slider "iceSlideShow", in the dock it says that you need to create a category and shove materials, this will be the slides. However, I change the slider / article, nothing changes. I've looked all over the admin panel and can't find anything.
