No post teaser on my home page- only heading

I am using the origin theme and have just created my first post. However, all you can see on my homepage is the title of the post. You have to then click on this title to see the full post.

Ideally I would like to see a teaser of my post on the homepage. Then, the ability to see the full post by clicking on it.

I have looked on a number of forums and tried playing around with ‘more’ ‘content’ and ‘excerpt’, but no luck.

Any help would be very much appreciated!!

Thanks in advance.
