+      # Mount the root folder where all your compose files live. 
+      # The path on the left (Host) MUST EXACTLY MATCH the path on the right (Container).
+      # EXAMPLE: If your compose files are in /opt/docker, use: - /opt/docker:/opt/docker
+      - /path/to/your/docker/folder:/path/to/your/docker/folder
+      
+      # (Optional but Recommended) Media/Data Drives

+    # ⚠️ GLOBAL ENVIRONMENT VARIABLES ⚠️
+    # If your compose files rely on host-level shell variables (like $PUID, $TZ)
+    # or a centralized globals.env file, you MUST pass them into Sencho here.
+    # Otherwise, Sencho will evaluate your compose files with empty variables.
+    # If you do not use a global env file, you can delete these two lines.
