+A FastAPI server that manages bot instances and provides endpoints for both Daily Prebuilt and Pipecat client connections.
 
 ## Endpoints
 
 - `GET /` - Direct browser access, redirects to a Daily Prebuilt room
-- `POST /connect` - RTVI client connection endpoint
+- `POST /connect` - Pipecat client connection endpoint
 - `GET /status/{pid}` - Get status of a specific bot process

+## Available Bots
+
+The server supports two bot implementations:
+
+1. **OpenAI Bot** (Default)
+
+   - Uses GPT-4 for conversation
+   - Requires OPENAI_API_KEY
+
+2. **Gemini Bot**
+   - Uses Google's Gemini model
+   - Requires GEMINI_API_KEY
+
+Select your preferred bot by setting `BOT_IMPLEMENTATION` in your `.env` file.
