Homepage – How to show post snippets only?

I just updated to the most recent version of Custom Community and it meant I had to reset a lot of my theme settings as it’s changed so much. I previously had it set up so my homepage would only show a snippet of each post, rather than the whole posts. However now it has reset to showing the whole posts on the homepage. How do I put this back to show only snippets of each post on the homepage? I’ve looked through all the settings but can’t find the option.
