+## Cookie Consent and Disabling Telemetry
+
+If you need to check if a user has already consented to cookies for GDPR compliance, you can specify a local storage key and value under `cookies`:
+
+```json
+  "integrations": {
+    "cookies": {
+      "key": "LOCAL STORAGE KEY",
+      "value": "LOCAL STORAGE VALUE"
+    }
+  }
+```
+
+If these values are set, local storage will be checked to see if the user has consented to cookies. If they have not, telemetry will be disabled.
+
+If you'd like to disable telemetry for all users, you can add the following to your `docs.json` file:
+
+```json
+  "integrations": {
+    "telemetry": {
+      "enabled": false
+    }
+  }
+```
