Read More button

Hi, how can I get the excerpts on my homepage for this “Rams” theme to show a “Read More” button?

In other words, my home page here:

https://thecollaboration.io/

doesn’t show the the “Read More” button at the bottom of a blog post excerpt.

But on Anders’s example theme here:

https://andersnoren.se/themes/rams/

it does show that button.

How do I enable it?

Thanks for any belp!
