-### Behind a Reverse Proxy
-
-Here are some example configurations for running LetterFeed behind a reverse proxy.
-
-#### Nginx
-
-```nginx
-server {
-    listen 80;
-    listen 443 ssl;
-    server_name letterfeed.leonmuscat.de;
-
-    # SSL configuration (assuming certs are managed elsewhere, e.g., Certbot)
-    ssl_certificate /etc/letsencrypt/live/letterfeed.leonmuscat.de/fullchain.pem;
-    ssl_certificate_key /etc/letsencrypt/live/letterfeed.leonmuscat.de/privkey.pem;
-    include /etc/letsencrypt/options-ssl-nginx.conf;
-    ssl_dhparam /etc/letsencrypt/ssl-dhparams.pem;
-
-    # Public Feeds (No Authentication)
-    location /api/feeds/ {
-        proxy_pass http://frontend:3000; # Assuming 'frontend' is the service name or IP
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-    }
-
-    # Secure Frontend (With Basic Auth)
-    location / {
-        auth_basic "Restricted Area";
-        auth_basic_user_file /etc/nginx/conf.d/htpasswd; # Path to your htpasswd file
-
-        proxy_pass http://frontend:3000; # Assuming 'frontend' is the service name or IP
-        proxy_set_header Host $host;
-        proxy_set_header X-Real-IP $remote_addr;
-        proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
-        proxy_set_header X-Forwarded-Proto $scheme;
-    }
-}

-
-#### Traefik
-
-Create a docker-compose.override.yml with 2 routers for feeds and everything else.
-
-```yaml
-services:
-  frontend:
-    ports: !override []
-    labels:
-      - "traefik.enable=true"
-      - "traefik.http.services.frontend.loadbalancer.server.port=3000"
-      - "traefik.docker.network=traefik_web"
-
-      # --- Router for Public Feeds (No Authentication) ---
-      - "traefik.http.routers.frontend-public.rule=Host(`letterfeed.leonmuscat.de`) && PathPrefix(`/api/feeds/`)"
-      - "traefik.http.routers.frontend-public.priority=10"
-      - "traefik.http.routers.frontend-public.entrypoints=websecure"
-      - "traefik.http.routers.frontend-public.tls.certresolver=myresolver"
-
-      # --- Router for Secure Frontend (With Basic Auth) ---
-      - "traefik.http.routers.frontend-secure.rule=Host(`letterfeed.leonmuscat.de`)"
-      - "traefik.http.routers.frontend-secure.priority=5"
-      - "traefik.http.routers.frontend-secure.entrypoints=websecure"
-      - "traefik.http.routers.frontend-secure.tls.certresolver=myresolver"
-      - "traefik.http.routers.frontend-secure.middlewares=frontend-auth@docker"
-      - "traefik.http.middlewares.frontend-auth.basicauth.users=test:$apr1$ruV6b18i$9J0V2yJ94jL0g08xJ2Q0Q/"
