+# Styles CSV Loader Extension for ComfyUI
+Extension for [ComfyUI](https://github.com/comfyanonymous/ComfyUI) that loads styles from a CSV file.
+## Description
+This extension allows users to load styles from a CSV file, primarily for migration purposes from the [automatic1111 Stable Diffusion web UI](https://github.com/AUTOMATIC1111/stable-diffusion-webui). 
+
+**Important**: The `styles.csv` file must be located in the root of `ComfyUI` where `main.py` resides. You can also symlink it if necessary. 
+
+Example of symlinking:
+```bash
+ln -s /path/to/your/styles.csv /path/to/ComfyUI/styles.csv
+```
+
+## Nodes Description
+Each style is represented as a dictionary with the keys being `style_name` and the values being a list containing `positive_prompt` and `negative_prompt`. The prompts are outputs of this Node.
