 This incubation is attempting to specify an API for user agents that would mediate access to, and representation of, verifiably-issued digital credentials.
 
 These identities can range from government-issued documents, such as driver's licenses and passports, to start with, to other credential types, potentially in the future.
 
-The [Digital Credential API](https://wicg.github.io/digital-identities/) builds upon the [Credential Management standard](https://www.w3.org/TR/credential-management-1/) to enable the secure and private exchange of digital identity information. It facilitates authenticated interactions by representing digital credentials through the `DigitalIdentity` interface, which embodies verifiable claims about an individual's identity.
