-**ComfyUI-Manager** is an extension that allows you to easily install, update, and manage custom nodes for ComfyUI.
-
-### Setup
-
-1. Install the manager dependencies:
-   ```bash
-   pip install -r manager_requirements.txt
-   ```
-
-2. Enable the manager with the `--enable-manager` flag when running ComfyUI:
-   ```bash
-   python main.py --enable-manager
-   ```
-
-### Command Line Options
-
-| Flag | Description |
-|------|-------------|
-| `--enable-manager` | Enable ComfyUI-Manager |
-| `--enable-manager-legacy-ui` | Use the legacy manager UI instead of the new UI (requires `--enable-manager`) |
-| `--disable-manager-ui` | Disable the manager UI and endpoints while keeping background features like security checks and scheduled installation completion (requires `--enable-manager`) |
