Excerpts rather than full posts

I really like the simplicity yet elegance of Anders Noren’s WordPress themes. Currently I’m using Hemingway. The only change I make is to show excerpts rather than full posts on the front and summary pages. This is easily done by editing the theme file directly. The change needed is to access Appearance – Editor in the admin panel, select file content.php and change line 65 (which may change) from

<?php the_content(); ?>

to

<?php the_excerpt(); ?>

Clearly this change can be overwritten by a theme update, thus this post for posterity.
