-### Receiving messages ###
+## Requirements
 
-The following utility method allows you to easily process messages sent from the BOT API platform via a Callback URL.
+This library requires Go 1.6 or later.

+## LICENSE
 
-```go
-	http.HandleFunc("/callback", func(w http.ResponseWriter, req *http.Request) {
-		received, err := bot.ParseRequest(req)
-		if err != nil {
-			if err == linebot.ErrInvalidSignature {
-				w.WriteHeader(400)
-			} else {
-				w.WriteHeader(500)
-			}
-			return
-		}
-		for _, result := range received.Results {
-			content := result.Content()
-			if content != nil && content.IsMessage && content.ContentType == linebot.ContentTypeText {
-				text, err := content.TextContent()
-				_, err := bot.SendText([]string{content.From}, "OK " + text.Text)
-				if err != nil {
-					log.Println(err)
-				}
-			}
-		}
-	})
-	if err := http.ListenAndServe(":8080", nil); err != nil {
-		log.Fatal(err)
-	}
-```

-		...
-		for _, result := range received.Results {
-			content := result.Content()
-			if content != nil && content.IsMessage && content.ContentType == linebot.ContentTypeImage {
-				res, err := bot.GetMessageContent(content)
-				if err != nil {
-					return
-				}
-				defer res.Content.Close()
-				image, err := jpeg.Decode(res.Content)
-				if err != nil {
-					return
-				}
-				log.Printf("image %v", image.Bounds())
-			}
-		}
-	})
-```
-
-### Getting previews of message content ###

-
-```go
-	http.HandleFunc("/callback", func(w http.ResponseWriter, req *http.Request) {
-		...
-		for _, result := range received.Results {
-			content := result.Content()
-			if content != nil && content.IsMessage && content.ContentType == linebot.MessageContentTypeImage {
-				res, err := bot.GetMessageContentPreview(content)
-				if err != nil {
-					return
-				}
-				defer res.Content.Close()
-				image, err := jpeg.Decode(res.Content)
-				if err != nil {
-					return
-				}
-				log.Printf("image %v", image.Bounds())
-			}
-		}
-	})
