-2.搜索节点
-3.节点、组件属性实时显示更改
-4.圈出节点位置
-5.输出节点、组件引用到控制台
+- 场景节点树实时显示，节点、组件属性实时显示更改

-## 已知问题
+## 项目使用
 
-- 当升级 Cococs Creator 时会清空resources目录，需要重新下载配置，如自定义了一些配置，请做好备份。
-- 开启节点树会增加渲染消耗，非调试阶段请关闭。
+Cocos Creator 从 v2.2 开始新增了自定义网页预览功能。
+
+1. 重复上面的操作步骤，将修改后的 `preview-templates` 目录拷贝到项目根目录
+
+2. 将 `ccc-devtools/index.html` 里所有引用的资源路径 `app/editor/static/preview-templates/ccc-devtools/...` 替换为 `ccc-devtools/...`
+
+3. 重启 Cocos Creator
+
+## 自定义
+
+- 本项目使用了 vue 和 vuetify，可根据 [vuetify 文档](https://vuetifyjs.com/en/getting-started/quick-start/) 对页面进行修改
+
+- 节点、组件显示属性可在 `config.js` 里配置，目前支持 text，number，textarea，color，bool 几种类型
