+### Headers set on NGINX
+
+It is possible to set any additional header
+
+| Parameter                    | Description                         | Default   |
+|------------------------------|-------------------------------------|-----------|
+| `nginx.config.headers.<key>` | Headers which are added with nginx  |           |
+
+
+Following keys are already set with this values:
+  - Referrer-Policy: `no-referrer`
+  - X-Content-Type-Options: `nosniff`
+  - X-Download-Options: `noopen`
+  - X-Frame-Options: `SAMEORIGIN`
+  - X-Permitted-Cross-Domain-Policies: `none`
+  - X-Robots-Tag: `noindex, nofollow`
+  - X-XSS-Protection: `1; mode=block`
+
+Maybe you like to set:
+  - Strict-Transport-Security: `max-age=15768000; includeSubDomains; preload;`
+> [!WARNING]
+> Only add the preload option once you read about
+> the consequences in https://hstspreload.org/. This option
+> will add the domain to a hardcoded list that is shipped
+> in all major browsers and getting removed from this list
+> could take several months.

 ### Probes Configurations
 
 The nextcloud deployment includes a series of different probes you can use to determine if a pod is ready or not. You can learn more in the [Configure Liveness, Readiness and Startup Probes Kubernetes docs](https://kubernetes.io/docs/tasks/configure-pod-container/configure-liveness-readiness-startup-probes/).
