+### Consent Logging
+The package provides the ability to track the users decisions by storing the chosen consent identifiers along with a random user id and the user agent in your database. This feature is disabled by default, you can enable it in your Settings.yaml:
+```yaml
+KaufmannDigital:
+  GDPR:
+    CookieConsent:
+      consentLogEnabled: true
+```
