+# ComfyUI Loop Node
+
+Custom node that provides loop (for-loop) functionality in ComfyUI.
+This allows you to repeat execution steps by outputting a list of integers, which triggers ComfyUI's list execution behavior.
+
+## Features
+
+- **For Loop (Count)**: Simple loop that runs `N` times. outputs `0` to `N-1`.
+- **For Loop (Range)**: Loop based on python `range(start, stop, step)`.
+
+## Installation
+
+Navigate to your `ComfyUI/custom_nodes/` directory and clone this repository:
+
+```bash
+git clone https://github.com/t22m003/ComfyUI_LoopNode.git
+```
+
+## Usage
