Adding a Slide
To create a new slide click on the plus icon in the menu bar next to "Slides":
This will take you to a page on which you can enter a title and a description for your slide. Title and description will eventually show up in the Module Page, e.g. the title is shown in the slides list and the description is shown as info box.
Once you've created a slide, you will be redirected to the same module page for which you have created the slide.
This page contains the following topics:
Editing a Slide
You can edit the name of the Slide and the description by clicking the 
icon. Each Slide consists of Text Blocks and Image Blocks representing text and images.
You can use the "Add content" dropdown and select either "Add Text" or "Add Image" based on what needs to be added for a particular slide.
Slide with Content Blocks
This is typically how a slide would look with Text blocks and Image blocks included.
