IDE Development Environment Installation
Currently, there are two popular Go IDEs: VSCode+Plugins (free) and JetBrains's Goland (paid). As JetBrains is also a sponsor of the GoFrame framework, we recommend using Goland as the development IDE. For download and registration, please refer to online tutorials (Baidu or Google).
JetBrains official website: https://www.jetbrains.com
Using Goland
Let's create the first Go program, following the usual convention with hello world.
Step 1. Open IDE
Step 2. Create Project
Note the Go installation file path (SDK), which is thoroughly explained in the official installation documentation, so please read it carefully.
The Location can be any local path you choose.

package main
import "fmt"
func main() {
fmt.Println("hello world!")
}
Step 4. Run Execution

Congratulations, your first Go program is successful!
