How do I unpublish my site while I am setting it up?

If you are setting up your site and would like to keep it unpublished, you can do this by clicking the "Unpublish Your Site" button on the "Pages" menu.

This will keep it unpublished to the general public but will allow you to continue working on the site. Once you are ready to publish it, you can come back to the "Pages" menu and click "Publish Your Site".
