This post has a left hand sidebar. When this layout option is selected, a widget area will be added to the left hand side of the post. You can add widgets either in the customizer or by going to Appearance > Widgets in your WordPress dashboard.
The rest of this post is simply filler. You can read it if you’d like, but it wasn’t written with that in mind. Posts are rarely that short so this text just gives a bit of context for you to look at the page. What do you think?
I completely agree.
