How to Display Excerpts on WordPress Posts

1. Log in to your WordPress dashboard and display the post editing screen by opening the 'Posts' menu on the left side. Click either 'Add New' or the 'Edit' link under an existing post.
2. Click the 'Screen Options' pull-down menu in the top-right corner of the screen. This displays a menu allowing you to customize the options the WordPress displays on the post editing screen.

3. Click the 'Excerpt' check box to select it, and then click 'Screen Options' again to retract the menu.
4. Scroll below the main text entry area of the post editing screen. You should now see a field labeled 'Excerpt.'
5. Type the summary you would like to use for your post in the 'Excerpt' field, and then publish or update the post to begin using it instead of the default post summary.
