Hide details from home page

Hi,
I was wondering if it was possible to make it so that the home page didn’t show all of my new posts, or at least didn’t show them in their entirety. Every time I make a new post, the home page shows it whole. I want people to only see a small bit of it, and see the whole thing only after they click on the title.

How can I do this?

PS: If you visit my blog https://www.rusnarod.com/blog you will see that the post that i have up on the main page is shows in its entirety. I only want it show a little bit.

Thanks
