+## 为什么要做 devTool 插件
+让Horizon开发者获得更好的开发体验，获取准确的组件树结构、状态信息和真实dom对应关系。
+
+## 上下文关系
+devTool功能的实现依赖浏览器 extension 开放的能力，用于绘制展示组件信息和获取真实 dom 元素。同时也需要 Horizon 提供相关接口获取组件树信息和提供调试能力。
+
+## 目标
+1. 查看组件树结构并支持过滤
+2. 查看组件与真实dom的关系
+3. 查看组件props, state, hooks 等信息
+4. 调试单个组件及其子组件
+5. 支持状态管理解决方案调试

+Helper: 提供接口给插件操控组件以及提供工具方法。
+Parser: 负责将组件树结构和组件信息解析成特定的数据结构，供Panel展示。
