[Harmonic] How to set excerpt format on front page of the blog?

Hi,

it’s kind of desperate now, I have to ask it here. I’ve been started off wordpress awhile now but it’s still pretty confusing and complicated on codes for me.

I’ve been tackling the excerpt problem awhile now but I just can’t make my front page to display it. I can find the_content nowhere, I’m using the Harmonic theme, I checked index.php, content-front-page.php and even front-page.php under the template folder.

There’s a <?php the_content ?> in the content-front-page.php but it doesn’t work when I changed the code.

More even, I checked the default themes to tried to get some insights but there’s no the_content at their index.php at all, twentyfifteen, twentysixteen that sort.

I started to wonder is it patch updates that the template is changed to some other files now?

Thank you.
