+# 【待办事项提醒小程序】微信公开课Pro 小程序云开发项目实战
+
+## 项目介绍
+
+此处为项目完整代码，可以直接部署使用；以下是现场部署步骤：
+
+- 初始化云开发环境，如果有多个云开发环境造成wx.cloud.init错误，则在app.js处进行环境定义。
+- 在云开发环境中创建一个数据库，名称为messages
+- 前往微信小程序平台，选用小程序类别【办公-效率】，之后申请订阅消息模板，模板名称为【待办事项提醒】，编号4630
+- 将申请到的模板ID复制到miniprogram/pages/index/index.js文件的第2行，lessonTmplId后面
+- 将cloudfunctions文件夹内的2个云函数创建并部署，并将send云函数上传触发器
+
+## 实战作者
+- 腾讯云·云开发团队（[bestony](https://github.com/bestony)、[lidongyx](https://github.com/lidongyx)、[Zira](https://github.com/wasfzxt)）

+## 参考文档
