+# Referencing Trust Registry within a Verifiable Credential
+
+Trust Registries are referenced within **Accreditaiton Policies** in the Verifiable Credential body. This enables Relying Parties to traverse the trust chain and verify that the **issuer**, accrediting entity (**TAO**) and Root of Trust (**rTAO**) are all legitimate entities.
+
+Within the body of the Verifiable Credential, issuers will need to configure the `termsOfUse` section to reference DIDs or DID URLs of trust registry entries, for example:
+
+```json
+{
+  "@context": [
