 ## Getting started

 ### Prerequisites

- **[Go](https://go.dev/)**: any one of the **three latest major** [releases](https://go.dev/doc/devel/release) (we test it with these).
+Gin requires [Go](https://go.dev/) version [1.23](https://go.dev/doc/devel/release#go1.23.0) or above.

 ### Getting Gin

-With [Go module](https://github.com/golang/go/wiki/Modules) support, simply add the following import
+With [Go's module support](https://go.dev/wiki/Modules#how-to-use-modules), `go [build|run|test]` automatically fetches the necessary dependencies when you add the import in your code:

-```
+```sh
 import "github.com/gin-gonic/gin"
 ```

-to your code, and then `go [build|run|test]` will automatically fetch the necessary dependencies.
-
-Otherwise, run the following Go command to install the `gin` package:
+Alternatively, use `go get`:

 ```sh
-$ go get -u github.com/gin-gonic/gin
+go get -u github.com/gin-gonic/gin
 ```

 ### Running Gin

-First you need to import Gin package for using Gin, one simplest example likes the follow `example.go`:
+A basic example:

 ```go
 package main
@ -72,29 +70,29 @@ func main() {
 }
 ```

-And use the Go command to run the demo:
+To run the code, use the `go run` command, like:

-```
-# run example.go and visit 0.0.0.0:8080/ping on browser
-$ go run example.go
+```sh
+go run example.go
 ```

-### Learn more examples
+Then visit [`0.0.0.0:8080/ping`](http://0.0.0.0:8080/ping) in your browser to see the response!
