You must be an Admin to create and permission a Collection.
Creating a Collection
Navigate to the Collections page and click the Create new Collection button. Fill in the details in the pop-up menu to build a Collection from scratch.
You can also navigate to the Collections tab within Team Settings and click Create a new Collection. From the pop-up menu, you can choose to start from scratch with a blank Collection, or, choose to start with a pre-populated Collection Framework.
Collection Frameworks contain pre-built Boards and suggestions for types of Cards to help your team build and organize your own knowledge quickly.
Adding Collection Details
If you chose to start with a blank Collection, name the Collection and add a description. You can edit the Collection's name and description later by clicking the gear icon and selecting Collection Settings.
Pick a Group to be the Collection Owner.
Choose the color of the Collection. Colors help your team distinguish Collections from each other.
In the General Collection or a pre-populated framework, you will automatically be the individual Collection Owner until you select another Group. In any other Collection that you create from scratch, you can select any Group to be the Collection Owner.
