An account is how Content Controller distributes content and a license is the mechanism for putting limits on how content is accessed from a specific LMS or learning application. If you distribute content to multiple clients, you would set up an Account for each client. If you are using Content Controller to manage course distribution across internal systems, you would create an Account for each internal LMS.
Accounts represent groups of users who access content from an LMS. You can add content that has been previously uploaded to Content Controller to an account, and then share it as a small proxy package (also called a "dispatch" package) that can be imported into an LMS and then launched to deliver the content from Content Controller. You can use licenses to control access to an account's content.
Content Controller's account and license management features can be accessed by clicking on the "Accounts" button on the top navigation bar.
