+# Go_tutorial
+This is a tutorial to guide the learning for the programming language Go.
+## Structure and Compilation
+Let's first create a file called "Hello_JOJ.go", and write in:
+```go
+package main
+
+import (
+    "fmt"
+)
+
+func main(){
+    fmt.Println("Hello "+ "JOJ")
+}
+```
+Observe the structure it is similar to both Python and C++, as it needs to import certain library and need some special package to run the program. We will also see further that the syntax of Go is like the combination of both C++ and Python.
+
+If you want to run the program, you can either choose to directly run it:
+```bash
+$ go run Hello_JOJ.go
+```
+or choose to compile it as a binary file:
+```bash
+$ go build Hello_JOJ.go
+$ ./Hello_JOJ
+```
