If your organization has enabled this feature and enabled your access, promoting collections to your home dashboard serves as a way to curate and promote content for your entire organization.
To get started, make a collection of the content you would like to promote or select an already existing collection in your bottom collection drawer. Once a collection is selected, from your collection tools, select the "Share collection" option and then on the next screen, the option to "Create New Dash Tile".
On this screen, you'll be able to fine tune this promoted content including renaming, selecting the main image and visibility. Once the new dash is "created" it will be visible on your home dashboard.
