+# ComfyUI-ngrok
+Use ngrok to allow external access to ComfyUI.
+
+*It is not a custom node.
+
+## Installation: 
+
+1. Use `git clone https://github.com/pkpkTech/ComfyUI-ngrok` in your ComfyUI custom nodes directory
+2. Use `pip install -r requirements.txt` in ComfyUI-ngrok directory
+3. Open the __init__.py file in a text editor, replace None on line 12 with your ngrok Authtoken and save.
+
+If the preparation is successful, you will find the URL in the console when you start ComfyUI.
+
+If this does not work, adding `--enable-cors-header` to the ComfyUI execution argument may help.
