+# aw-webui
+
+ActivityWatch 的 Web 界面，使用 Vue.js 构建
+
+[![构建状态](https://github.com/ActivityWatch/aw-webui/workflows/Build/badge.svg)](https://github.com/ActivityWatch/aw-webui/actions)
+[![覆盖率](https://codecov.io/gh/ActivityWatch/aw-webui/branch/master/graph/badge.svg)](https://codecov.io/gh/ActivityWatch/aw-webui)

+
+## 快速开始
+
+设置开发环境非常简单：
+
+```bash
+# 以测试模式启动 aw-server 实例（端口 5666，使用独立数据库）
+# 开发模式下 Web UI 默认连接到此实例
+aw-qt --testing
+# 或不带监控器运行：
+aw-server --testing
+
+# 安装依赖
+npm install
+
+# 以开发模式运行（带有热重载）
+npm run serve
+
+# 构建生产版本
+npm run build
+```
+
