How do that?!

I am working on a college website and need badly to know how this WP powered site got multiple category posts on their home page. https://collegian.csufresno.edu/ on my site https://catalystonline.freehostia.com i took off all of the posts on the home page, but am trying to set up the format for the different category articles with the snippet of the article with the “readmore” link…

any suggestions on how to do what that site did or any ideas for format is greatly appreciated! thank you!
