 1. Add comments to your API source code, [See Declarative Comments Format](https://github.com/swaggo/swag/blob/master/README.md#declarative-comments-format).
 2. Download [Swag](https://github.com/swaggo/swag) for Go by using:
 
+---
 ```sh
 go get -u github.com/swaggo/swag/cmd/swag
 ```
+---
 
 Starting in Go 1.17, installing executables with `go get` is deprecated. `go install` may be used instead:
 
+---
 ```sh
 go install github.com/swaggo/swag/cmd/swag@latest
 ```
+---
 
 3. Run the [Swag](https://github.com/swaggo/swag) at your Go project root path(for instance `~/root/go-project-name`),
    [Swag](https://github.com/swaggo/swag) will parse comments and generate required files(`docs` folder and `docs/doc.go`)
    at `~/root/go-project-name/docs`.
 
+---
 ```sh
 swag init
 ```
+---
 
 4. Download [gin-swagger](https://github.com/swaggo/gin-swagger) by using:
 
+---
 ```sh
 go get -u github.com/swaggo/gin-swagger
 go get -u github.com/swaggo/files
 ```
+---
 
 Import following in your code:
 
+---
 ```go
 import "github.com/swaggo/gin-swagger" // gin-swagger middleware
 import "github.com/swaggo/files" // swagger embed files
 
 ```
+---
 
 ### Canonical example:
 
 Now assume you have implemented a simple api as following:
 
+---
 ```go
 // A get function which returns a hello world string by json
 func Helloworld(g *gin.Context)  {
 	g.JSON(http.StatusOK,"helloworld")
 }
 
 ```
+---
 
 So how to use gin-swagger on api above? Just follow the following guide.
 
 1. Add Comments for apis and main function with gin-swagger rules like following:
 
+---
 ```go
 // @BasePath /api/v1

 2. Use `swag init` command to generate a docs, docs generated will be stored at `docs/`.
 3. import the docs like this:
    I assume your project named `github.com/go-project-name/docs`.
 
+---
 ```go
 import (
    docs "github.com/go-project-name/docs"
 )
 ```

 4. build your application and after that, go to http://localhost:8080/swagger/index.html ,you to see your Swagger UI.
