+# Universal LLM Node for ComfyUI
+
+これは、ComfyUIで以下のLLM APIと接続してプロンプト拡張を行うためのノードです：
+
+- OpenAI (ChatGPT)
+- Claude (Anthropic)
+- Gemini (Google)
+- Groq
+- Mistral
+
+## 導入方法
+
+1. このリポジトリを `ComfyUI/custom_nodes/` に配置
+2. `.env` に各サービスのAPIキーを記載：
+
+```
+OPENAI_API_KEY=sk-...
+ANTHROPIC_API_KEY=sk-ant-...
+GOOGLE_API_KEY=...
+GROQ_API_KEY=...
+MISTRAL_API_KEY=...
+```
+
+3. 必要パッケージをインストール：
+
+```bash
+source venv/bin/activate
+pip install -r requirements.txt
+```
+
+4. ComfyUIを再起動すれば、`Universal LLM Prompt` ノードが使えるようになります。
