+2. **Core → Additional**: HTTP (internal network, no encryption needed)
+3. **Additional → Core**: HTTP (direct response to core Traefik)

 ## Step 1: Deploy Core Server

 **No Port Forwarding Required**:
 - Services are accessed through core server
-- Additional servers are "headless" - no external ports needed
 
 ## How It Works
 
 ### Traffic Flow
 
-1. **User accesses** `https://sonarr.yourdomain.duckdns.org`
-2. **Core Traefik** receives request:
+1. **User accesses** `https://sonarr.yourdomain.duckdns.org` (HTTPS from internet)
+2. **Core Traefik** receives HTTPS request:
    - Checks Authelia for authentication (SSO)
-   - Routes to additional server: `http://192.168.1.100:8989` (via YAML config)
+   - Routes to additional server: `http://192.168.1.100:8989` (HTTP internally)
 3. **Additional server** receives direct HTTP request:
    - Service container receives request on exposed port
    - If stopped, Sablier starts the container
    - Shows loading page while container starts
-4. **Service responds** directly back to core Traefik, then to user
+4. **Service responds** directly back to core Traefik via HTTP, then HTTPS to user

+### Key Points
+
+- **External Traffic**: Always HTTPS (SSL/TLS encrypted)
+- **Internal Traffic**: Always HTTP (no encryption needed on local network)
+- **No Double Encryption**: Core Traefik terminates SSL, forwards plain HTTP internally
