By clicking on the name of an issue in the Issue List, you will enter the Section List. At first, a new issue will have no sections.
If you click on the 'Add new section' link, you will see the corresponding page appear.
Here you must specify the Name, section Number, and URL name. While you can change the name of the section later, the section number is set at the time when the new section is added. The URL name will be part of the URL if you are used the "short names" option when you created the publication.
The section Description is optional. This field is useful for displaying content that doesn't change very often. The information in this field will only be displayed on your site if the template you are using supports it. If you would like to make the new section available to all existing subscribers, you should check the box for this option. Then click the Save button.
Your next step is to set the templates for the new section on the Configure Section page.
Here, you may wish to select custom templates for this new section and its articles from the drop-down menus. If you don't have custom templates for specific sections, you can use general section and article templates instead.
