+### did:prism AnonCreds Method
+
+The `did:prism` AnonCreds Method specifies how to register and resolve AnonCreds objects as general purpose resources through the [PRISM DID Method](https://github.com/input-output-hk/prism-did-method-spec/blob/main/w3c-spec/PRISM-method.md). The identifiers for the resources are DID URLs that are dereferenced to return the AnonCreds objects.
+
+This method is defined upon the PRISM DID Method, however, it can be implemented on top of any DID method that supports [services](https://www.w3.org/TR/did-core/#services).
