+
+As a voice interaction entry, the XiaoZhi AI chatbot leverages the AI capabilities of large models like Qwen / DeepSeek, and achieves multi-terminal control via the MCP protocol.

+
+## Version Notes
+
+The current v2 version is incompatible with the v1 partition table, so it is not possible to upgrade from v1 to v2 via OTA. For partition table details, see [partitions/v2/README.md](partitions/v2/README.md).
+
+All hardware running v1 can be upgraded to v2 by manually flashing the firmware.
+
+The stable version of v1 is 1.9.2. You can switch to v1 by running `git checkout v1`. The v1 branch will be maintained until February 2026.

+## Software
+
+### Firmware Flashing
+
+For beginners, it is recommended to use the firmware that can be flashed without setting up a development environment.
+
+The firmware connects to the official [xiaozhi.me](https://xiaozhi.me) server by default. Personal users can register an account to use the Qwen real-time model for free.
+
+👉 [Beginner's Firmware Flashing Guide](https://ccnphfhqs21z.feishu.cn/wiki/Zpz4wXBtdimBrLk25WdcXzxcnNS)
+
+### Development Environment
+
+- Cursor or VSCode
+- Install ESP-IDF plugin, select SDK version 5.4 or above
+- Linux is better than Windows for faster compilation and fewer driver issues
+- This project uses Google C++ code style, please ensure compliance when submitting code
+
+### Developer Documentation
+
+- [Custom Board Guide](docs/custom-board.md) - Learn how to create custom boards for XiaoZhi AI

+- [A detailed WebSocket communication protocol document](docs/websocket.md)
+
+## Large Model Configuration
+
+If you already have a XiaoZhi AI chatbot device and have connected to the official server, you can log in to the [xiaozhi.me](https://xiaozhi.me) console for configuration.
