 CGO is an official builtin feature of Go, it enables the creation of Go packages that reference to C libraries. But it isn’t just that, it is achievable in the opposite direction, too. It enables creation of C libraries from Go packages so that C code can reference to Go, which is mind-blowing.
 
+CGO 不但可以使 Go 包访问 C 库，还可以通过 Go 包创建 C 库。
+
 ## 1.How to
 
 ### 1.1.Build Go package as C shared library (or shared object)
 
 Every Go **main** package can be built as a C shared library.
 
+任何 Go **main** 包都可以创建 C 库。
+
 ```bash
-go build -go build -buildmode c-shared -o <c-lib>.so <go-package>
+go build -buildmode=c-shared -o <c-lib>.so
 ```
 
 Executing above command builds target Go **main** package and all of its dependencies as a single C shared library, which can be distributed, installed and linked to every C application and applications in other programming languages that can reference C shared libraries (C++, Python, Javascript, etc).
 
+以上命令可以创建共享库，该共享库可以被 C、C++、Python、Javascript 等语言访问。
+
 Note: Output C shared libraries should be named in standard form **lib\*.so**.

 To export a Go function as a C symbol:
 
-* Add comment **//export FuncName** on top of the Go function.
-* The Go code file containing the function has to **import "C"**.
 * The function must belong to **main** package.
+* The Go code file containing the function has to **import "C"**.
+* Add comment **//export FuncName** on top of the Go function.
 * The function signature must not include neither Go struct nor* Go interface nor Go array nor variadic argument.
 
+上述命令不会生成 C 头文件并导出符号。若想导出符号并自动生成头文件需要满足以下条件：
+
+* 要导出的函数必须属于 **main** 包；
+* Go 源码文件包含 **import "C"**；
+* 在要导出的函数使用 **//export FuncName** 注释；
+* 不能使用 Go struct、Go interface、Go arra、以及可变参数。
