We have added a new stage type to the multi-stage promotions called Descriptive Content. 

With the Descriptive Content stage, you can show participants an image or a video, accompanied by text, along with a button that can take the user to an external website. 

The stage uses the Story format and the administrator of the promotion can customize everything: background color, background image, media to show, text and the text color, highlight color, and the color, link, and text of the button. You can also adapt the padding of the content and choose if you want to give points for participating in the stage.

Please see the tutorial to learn how to set up the Descriptive Content-stage.
