+
+## Background
+
+This test suite provides conformity tests for identifiers that support the
+[W3C Controlled Identifiers (CIDs) v1.0](https://www.w3.org/TR/cid/).
+
+## Install
+
+```js
+npm i
+```
+
+## Setup
+
+Have a W3C Controlled Identifiers (CIDs) v1.0 document available on the web. The test-suite will do a GET request on the provided identifier.
+
+## Usage
+
+```sh
+npm test
+```
+
+### Testing Locally
+
+To test a single implementation or endpoint running locally, you can
+copy `localConfig.example.cjs` to `localConfig.cjs`
+in the root directory of the test suite.
+
+```bash
+cp localConfig.example.cjs localConfig.cjs
+```
+
+This file must be a CommonJS module that exports an object containing a
+`settings` object (for configuring the test suite code itself) and an
+`implementations` array (for configuring the implementation(s) to test against).
+
+The format of the object contained in the `implementations` array is
+identical to the one defined in
+[the **_Testing locally_** section of VC Test Suite Implementations](https://github.com/w3c/vc-test-suite-implementations?tab=readme-ov-file#testing-locally).
+The `implementations` array may contain more than one implementation object,
+enabling you to test multiple implementations in one run.
+
+```js
+// localConfig.cjs defines local implementations
+module.exports = {
+  implementations: [{
+    name: 'My Company',
+    implementation: 'My Implementation Name',
+    issuers: [{
+      id: 'https://example.com'.
+      tags: ['cid']
+    }]
+  }];
+```
+
+## Implementation
+
+To add your implementation to this test suite, add a test manifest describing
+your implementation to the
+[`w3c/vc-test-suite-implementations`](https://github.com/w3c/vc-test-suite-implementations)
+repo by following the
+[Adding a new implementation](https://github.com/w3c/vc-test-suite-implementations/tree/main?tab=readme-ov-file#adding-a-new-implementation)
+instructions.
+
+All endpoints will need the tag `vc2.0`. A simplified manifest will roughly
+look like the following:
+
+```js
+{
+  "name": "My Company",
+  "implementation": "My implementation",
+  "issuers": [{
+    "id": "https://example.com",
+    "tags": ["cid"]
+  }]
+}
+```
+
+See
+[Adding a new implementation](https://github.com/w3c/vc-test-suite-implementations/tree/main?tab=readme-ov-file#adding-a-new-implementation)
+for more information.
