Adding Content
To add content to a container, you first want to access the container by clicking on the list icon on either the container's image or the icon at the bottom of the card.
When you access a container, you will be taken to this view. Here, you can drag and drop files directly into this container or add them to a sub-container to keep things organized.
Clicking the plus sign in the bottom right-hand corner will give you the ability to Upload Resources, Record Videos, Add External Links, Copy from Library, and Create Container.
