 ## Arduino sketch examples
 
 After installing the library, some sketch examples are available from the *File* menu, then *Examples* and finally under *ESP8266-Arduino-Lua*. The examples include **ExecuteScriptFromSerial** which takes a lua script from the serial line and executes it:

 # ESP8266 Arduino Lua
 
-This Arduino library provides the [lua](https://www.lua.org/) 5.3.4 scripting engine for ESP8266 sketches. This allows dynamic execution of code on Arduino without having to compile and flash a new firmware. As an example, the following standard Arduino functions are available in lua scripts as bindings:
-* *pinMode()*
-* *digitalWrite()*
-* *delay()*
-* *millis()*
-* *print()* which redirects to *Serial.println()*

+- base (print(), tostring(), tonumber(), etc.)
+- math
+- table (insert(), sort(), remove(), ...)
+- string (len(), match(), ...)
+
+##  示例: ExecuteScriptFromSerial.ino
+
+安装本扩展后，在 *File* 菜单中的 *Examples* 下的 *Arduino-Lua* 中 会提供部分示例。示例中包含 **ExecuteScriptFromSerial** ，可以通过串口输入 Lua 脚本并执行。例如，如下的标准 Arduino 函数，可以被绑定从而在 lua 脚本中使用：
+
+- pinMode()
+- digitalWrite()
+- delay()
+- millis()
+- print() *(only builtin binding)*
+
+```
+# Enter the lua script and press Control-D when finished:
+# 输入如下的 lua脚本，然后按 Ctrl+D 运行:
