-## Intermediate Certificates
-
-Intermediate certificates are used to sign end-entity certificates (servers, clients). **Clients typically do not need to install these manually**, as servers should provide them during the handshake.
-
-**For Server Administrators:**
-To configure your web server (Nginx, Apache, IIS) with the full chain, please refer to the **[Web Server Configuration](/guide/integrations/web-servers)** guide.
-
-**Manual Installation (If Required):**
-If you must install them manually (e.g., for offline chain validation):
-*   **Windows**: Follow the Root CA guide, but choose **Intermediate Certification Authorities** as the certificate store.
-*   **macOS**: Add to **System** keychain.
-*   **Linux**: Place in the same CA directory as the Root.
