+{YELLOW}SD Prompt Reader Node{RESET} requires additional files that are missing.
+
+{BLUE}The Problem:{RESET}
+This node uses a git submodule that wasn't properly initialized during installation.
+
+{BLUE}How to Fix:{RESET}
+Run the following commands in your ComfyUI custom_nodes directory:
+
+{YELLOW}cd comfyui-prompt-reader-node
+git submodule init
+git submodule update{RESET}
+
+{BLUE}Current Directory:{RESET}
+{YELLOW}{os.path.dirname(os.path.abspath(__file__))}{RESET}
+
+{BLUE}Alternative Fix:{RESET}
+Reinstall using the recursive clone command:
+
+{YELLOW}git clone --recursive https://github.com/receyuki/comfyui-prompt-reader-node.git{RESET}
+
