Show Author, comment toals on home page

Right now, posts on the home page only show the date at the top. When you click on the post, it also shows the date.

What’s the best way to show the author and comment totals at the top on the home page? Like this…

DATE AUTHOR X COMMENTS
POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST POST
