 # Cross-Platform Edge SDK Verification
 ## Requirements
 1. A working Identus Mediator and an Identus Cloud Agent.
-2. A holder who already has a JWT Credential issued by a known issuer (prism:did) [Holder A]
+2. A holder who already has a JWT or Anoncred Credential issued by a known issuer (prism:did) [Holder A]
 3. A holder who does not have credentials but aims to start the Verification [Holder B (verifier)]
 4. Holder A shares its peerDID with holder B.
 5. Holder B will initiate a presentation request

 ## Flow
 1. Holder B Initiates the Presentation Request: creating a PresentationDefinitionRequest with specified requirements.
-2. Holder A, will then create a Presentation Submission which contains the requested credential together with a randomised challenge.
-3. Holder B, will receive the Presentation Submission and verify the following
-    * Holder A signed the JWT presentation with the correct signatures.
-    * Holder A signed the random challenge that required them to have the correct keys.
-    * Holder A includes a credential of its owns and not somebody else's.
-    * Holder A includes a credential with valid signatures, matching the issuer through the specified DID.
-    * (optional) Holder A has included a credential that the requested issuer has issued.
-    * (optional) Holder A has included a credential that satisfies the requested claims.
+2. Holder A, will then create a Presentation which meets the criteria received as part of the request.
+3. Holder B, will receive the Presentation and verify the following
+    * [JWT] Holder A signed the JWT presentation with the correct signatures.
+    * [JWT] Holder A signed the random challenge that required them to have the correct keys.
+    * [JWT] Holder A includes a credential of its owns and not somebody else's.
+    * [JWT] Holder A includes a credential with valid signatures, matching the issuer through the specified DID.
+    * [JWT] (optional) Holder A has included a credential that the requested issuer has issued.
+    * [JWT] (optional) Holder A has included a credential that satisfies the requested claims.
+    * [Anoncreds] Holder A presentation meets the attributes and predicates requested.
 4. Holder B can then verify at any point in time that presentation request and show feedback in UI.
