+# ComfyUI-VIBE 🎨
+
+Implementation of **VIBE** (Visual Instruction Based Editor) as a custom node for [ComfyUI](https://github.com/comfyanonymous/ComfyUI). Edit images using natural language instructions (e.g., "make it winter", "change the dog to a cat").
+
+VIBE leverages the efficient **Sana1.5-1.6B** diffusion model and **Qwen3-VL-2B-Instruct** for fast, high-quality image manipulation.
+
+---
+
+## ✨ Features
+- **Instruction-based Editing**: No complex prompting required.
+- **Latent Support**: Connect an `Empty Latent Image` to define output resolution.
+- **Fast Inference**: Powered by Sana1.5's linear attention.
+- **Local Model Support**: Runs entirely on your hardware.
+
+---
+
+## 🚀 Installation
+
+1. **Clone the repository**:
+   Navigate to your `ComfyUI/custom_nodes` folder and run:
+   ```bash
+   git clone https://github.com/ato-zen/ComfyUI-VIBE
+   ```
+
+2. **Install dependencies**:
+   Open terminal in the `ComfyUI-VIBE` folder and run:
+   ```bash
+   pip install -r requirements.txt
+   ```
+
+---
+
+## 📂 Model Setup
+
+This node looks for models in: `ComfyUI/models/vibe/`
+
+1. **Create the target folder**:
+   ```bash
+   mkdir -p models/vibe
+   cd models/vibe
+   ```
+
+2. **Download the weights**:
+   Clone from Hugging Face (requires [git-lfs](https://git-lfs.github.com/)):
+   ```bash
+   git clone https://huggingface.co/iitolstykh/VIBE-Image-Edit
+   ```
+
+Structure should look like:
+```text
+ComfyUI/models/vibe/
+└── VIBE-Image-Edit/
+    ├── model_index.json
+    ├── unet/
+    ├── vae/
+    ├── text_encoder/
+    └── tokenizer/
+```
