+## Quick Start
+
+### Download and install
+
+``` bash
+$ go get -u github.com/go-oauth2/gin-server
+```
+
+### Create file `server.go`
+
+``` go
+package main
+
+import (
+	"net/http"
+
+	"github.com/gin-gonic/gin"
+	"github.com/go-oauth2/gin-server"
+	"gopkg.in/oauth2.v3/manage"
+	"gopkg.in/oauth2.v3/store"
+)
+
+func main() {
+	manager := manage.NewDefaultManager()
+	manager.MustTokenStorage(store.NewMemoryTokenStore())
+	manager.MapClientStorage(store.NewTestClientStore())
+
+	// Initialize the oauth2 service
+	server.InitServer(manager)
+	server.SetAllowGetAccessRequest(true)
+
+	g := gin.Default()
+	g.GET("/token", server.HandleTokenRequest)
+	api := g.Group("/api")
+	{
+		api.Use(server.TokenAuth(func(c *gin.Context) string {
+			return c.Query("access_token")
+		}))
+		api.GET("/test", func(c *gin.Context) {
+			c.String(http.StatusOK, "ok")
+		})
+	}
+
+	g.Run(":9096")
+}
+```
+
+### Build and run
+
+``` bash
+$ go build server.go
+$ ./server
+```
+
+### Open in your web browser
+
+#### The token information
+
+```
+http://localhost:9096/token?grant_type=client_credentials&client_id=1&client_secret=11&scope=read
+```
+
+``` json

+    "expires_in": 7200,
+    "scope": "read",
+    "token_type": "Bearer"
+}
+```
+
+#### The authentication token
+
+```
+http://localhost:9096/api/test?access_token=ZF1M7NKDNWUUX2TCDIMZZG
