 ### 1. Get API Keys (at least one required)
+
+**Option A: OpenRouter (Access multiple models with one API)**
+- **OpenRouter**: Visit [OpenRouter](https://openrouter.ai/) for access to multiple models through one API. [Setup Guide](docs/openrouter.md)
+  - Control model access and spending limits directly in your OpenRouter dashboard
+  - Configure model aliases in `conf/openrouter_models.json`
+
+**Option B: Native APIs**
 - **Gemini**: Visit [Google AI Studio](https://makersuite.google.com/app/apikey) and generate an API key. For best results with Gemini 2.5 Pro, use a paid API key as the free tier has limited access to the latest models.
 - **OpenAI**: Visit [OpenAI Platform](https://platform.openai.com/api-keys) to get an API key for O3 model access.
 
+> **Note:** Using both OpenRouter and native APIs creates ambiguity about which provider serves each model. 
+> If both are configured, native APIs will take priority for `gemini` and `o3`.
