Before you add a new slide, please upload the image for the slide. You MUST upload an image that's 1200x720. You can upload images by going to New > _ALL > Images > Feature 1200x720
On the left side of the screen, navigate to [your site]/_cascade/blocks/primary feature. Your slides are stored within the primary feature folder.
Click on the first slide. Click Edit at the top of the screen. (To remove the slide, click Delete. To add another slide, click Copy.)
Fill in the Headline and Summary fields. The text in the Summary field will show up below your slide.
Click on the image icon beside the Image field and click Browse. Navigate to your images folder and click on the image that you want to be on your slide (the image MUST be 419x251). Click Confirm.
If you want the slide to link to a page that's in Cascade, click on the page icon beside the Page Link field. Click Browse, click on the page, and click Confirm. If you want the slide to link to a page outside of Cascade, enter the URL in the External URL field. If you don't want the slide to link at all, don't fill in either of those fields.
