 # ─── BETE GitLab CI/CD Pipeline ───────────────────────────────────────────────
-# Simply SSH into VPS → git pull → docker compose up -d --build
+# Builds 4 Docker images (frontend, backend, discord-gateway, proxy),
+# pushes to GitLab Container Registry, then deploys to VPS via SSH.
 #
 # Required CI/CD Variables (set in GitLab → Settings → CI/CD → Variables):
 #
-#   VPS_HOST        - VPS IP/hostname (e.g. 45.127.35.244)
-#   VPS_USERNAME    - SSH user (e.g. root)
+#   VPS_HOST        - VPS IP/hostname
+#   VPS_USERNAME    - SSH user
 #   VPS_SSH_KEY     - SSH private key (type: file)
+#   ENV_FILE        - Full .env file content (type: env_var)
 #
 # Notes:
-#   - VPS must have git access to this repo (deploy key or SSH agent)
-#   - .env file must already exist on VPS at $APP_DIR/.env
 #   - VPS_SSH_KEY must be "File" type so GitLab writes it to disk
+#   - ENV_FILE is "Variable" type — contains full multi-line .env content
