+# Tuya IoT Quick Start
+
+Tuya Cloud Application is an application provided by the Tuya IoT platform. With Tuya Cloud Application, developers can quickly implement remote device control, device management, and other functions.
+
+The `quickStart` demonstrates a simple, cross-platform, cross-system switch example that supports multiple connections. Through the Tuya APP and Tuya Cloud Service, you can remotely control this LED.
+
+## Product Creation
+
+Refer to the [Product Creation Documentation](https://developer.tuya.com/en/docs/iot-device-dev/application-creation?id=Kbxw7ket3aujc) to create a product on the [Tuya IoT](https://iot.tuya.com) platform and obtain the PID of the created product.
+
+Then replace the PID in `quickStart` with the PID you obtained.
+
+```c
+void setup() {
+  ...
+  TuyaIoT.begin("YOUR PID", PROJECT_VERSION);
+}
+```
+
+## Confirm TuyaOpen License Code
+
+Products developed through this project need to use the TuyaOpen-specific license code. Using other license codes will not connect to the Tuya Cloud properly.
+
+Modify the license code in the code as follows:
+
+```c
+// Tuya license
+#define TUYA_DEVICE_UUID    "uuidxxxxxxxxxxxxxxxx"
+#define TUYA_DEVICE_AUTHKEY "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
+```
+
+If you do not have a TuyaOpen license code, you can obtain it through the following methods:
+
++ Purchase a module with the TuyaOpen license code pre-burned. This license code is burned into the corresponding module at the factory and will not be lost. TuyaOpen reads the license code through the `TuyaIoT.readBoardLicense(&license);` interface at startup. Please confirm whether the current device has the TuyaOpen license code burned.
+
++ If the current module does not have the TuyaOpen license code burned, you can purchase the TuyaOpen license code through the [TuyaIoT platform](https://platform.tuya.com/purchase/index?type=6).
+
++ Obtain a free TuyaOpen license code through the following activities:
+
+  To allow developers to freely experience the TuyaOpen Framework, you can now get a free TuyaOpen Framework-specific license code by starring the TuyaOpen Framework repository on GitHub, including:
+
+  + [tuyaopen](https://github.com/tuya/tuyaopen)
+  + [arduino-tuyaopen](https://github.com/tuya/arduino-tuyaopen)
+  + [luanode-tuyaopen](https://github.com/tuya/luanode-tuyaopen)
+
+  With your GitHub account and screenshot, send an email to `[email protected]` or join the QQ group `796221529` and contact the group owner to receive a free TuyaOpen Framework-specific license code. Limited to 500 codes, first come first served, while supplies last. Scan the QR code below to join the group and claim your code👇:

+# Tuya IoT 快速上手
+
+涂鸦云应用是涂鸦 IoT 平台提供的一种应用，通过涂鸦云应用，开发者可以快速实现设备远程控制、设备管理等功能。
+
+`quickStart` 演示一个简单的，跨平台、跨系统、支持多种连接的开关示例，通过涂鸦 APP、涂鸦云服务，可以对这个 LED 进行远程控制。
+
+## 产品创建
+
+参考[产品创建文档](https://developer.tuya.com/cn/docs/iot-device-dev/application-creation?id=Kbxw7ket3aujc)，在 [Tuya IoT](https://iot.tuya.com) 平台上创建产品，并获取到创建产品的 PID 。
+
+然后在 `quickStart` 中 PID 替换为您创建得到的 PID。
+
+```c
+void setup() {
+  ...
+  TuyaIoT.begin("YOUR PID", PROJECT_VERSION);
+}
+```
+
+## 确认 tuyaopen 授权码
+
+通过该项目开发的产品需采用 TuyaOpen 专用授权码，使用其他授权码无法正常连接涂鸦云。
+
+在代码中修改授权码的位置如下：
+
+```c
+// Tuya license
+#define TUYA_DEVICE_UUID    "uuidxxxxxxxxxxxxxxxx"
+#define TUYA_DEVICE_AUTHKEY "xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
+```
+
+如果没有 tuyaopen 的授权码，可以通过下面的方式进行获取：
+
++ 购买已烧录 TuyaOpen 授权码模块。该授权码已经在出厂时烧录在对应模组中，且不会丢失。tuyaopen 在启动时通过 `TuyaIoT.readBoardLicense(&license);` 接口读取授权码。请确认当前设备是否为烧录了 tuyaopen 授权码。
+
++ 如当前模组未烧录 TuyaOpen 授权码，可通过 [TuyaIoT 平台](https://platform.tuya.com/purchase/index?type=6)购买 tuyaopen 授权码。
+
++ 通过下面的活动获取免费 TuyaOpen 授权码
+
+  为了让开发者们可以自由体验 Tuyaopen Framework，现在只要在 GitHub 上给 Tuyaopen Framework 开发框架仓库加 star，包括：
+
+  + [tuyaopen](https://github.com/tuya/tuyaopen)
+  + [arduino-tuyaopen](https://github.com/tuya/arduino-tuyaopen)
+  + [luanode-tuyaopen](https://github.com/tuya/luanode-tuyaopen)
+
+  凭 github 账号和截图，发送邮件至 `[email protected]` 或 加入 QQ 群 `796221529` 向群主免费领取一个 TuyaOpen Framework 专用授权码。限量 500 个，先到先得，送完即止，赶紧扫码加群来领👇：
