-### Tags
-Tags tell the test suites which tests should be run on your issuer, verifier,
-and status lists.
+### Opting into a Test Suite
 
-* `vc-api` - This tag will run the [vc-api-issuer tests](https://github.com/w3c-ccg/vc-api-issuer-test-suite) on your issuer and the [vc-api-verifier tests](https://github.com/w3c-ccg/vc-api-verifier-test-suite) on your verifier.
+Tags determine which test suites are executed on your issuers and verifiers.
 
-* `Ed25519Signature2020` - This tag will run the [Ed25519 tests](https://github.com/w3c/vc-di-ed25519signature2020-test-suite) on your issuer and/or verifier.
+* `vc-api` - This tag will run the [vc-api-issuer tests](https://github.com/w3c-ccg/vc-api-issuer-test-suite)
+on your issuer and the [vc-api-verifier tests](https://github.com/w3c-ccg/vc-api-verifier-test-suite)
+on your verifier.
 
-* `StatusList2021` - This tag will run the [Status List 2021 tests](https://github.com/w3c-ccg/status-list-2021-test-suite) on your issuer and/or verifier.
+* `Ed25519Signature2020` - This tag will run the [Ed25519 tests](https://github.com/w3c/vc-di-ed25519signature2020-test-suite) on your issuer and/or verifier.
 
-* `did-key` - This tag will run the [DID Key Test Suite](https://github.com/w3c-ccg/did-key-test-suite) on your DID resolver endpoint.
+* `StatusList2021` and `Revocation`/`Suspension`- Combining the `StatusList2021`
+tag with `Revocation` or `Suspension` tags will run the
+[Status List 2021 tests](https://github.com/w3c-ccg/status-list-2021-test-suite)
+on your issuer and/or verifier.
+  * Adding the `Revocation` tag alongside `StatusList2021` runs tests for
+  issuers or verifiers issuing/verifying VCs with the revocation status purpose.
+  * Adding the `Suspension` tag alongside `StatusList2021` runs tests for
+  issuers or verifiers issuing/verifying VCs with the suspension status purpose.
+  * Additional endpoints `setStatusLists` - `/credentials/status` and
+  `publishStatusLists` - `/credentials/publish` also may need to be specified
+  to update the status of VCs and publish the updated status.
+
+* `did-key` - This tag will run the [DID Key Test Suite](https://github.com/w3c-ccg/did-key-test-suite)
+on your DID resolver endpoint.
 
 * `ecdsa-rdfc-2019` or `ecdsa-sd-2023` - These tags will run the
 [VC Data Integrity ECDSA Test Suite](https://github.com/w3c/vc-di-ecdsa-test-suite)
 on your issuer and verifier endpoints.
-  * Alongside this cryptosuite tag, you must also specify the `supportedEcdsaKeyTypes`
-  key parallel to `tags` listing the ECDSA key types that your implementation issues or
-  can verify. Currently, the test suite supports `P-256` and `P-384` ECDSA key types.
