 ## Create a package for mobiles
 
-You need to create a package for mobiles with `github.com/hajimehoshi/ebiten/mobile` for your game. This package has exported functions to Java side.
-
-For an actual example, see [`github.com/hajimehoshi/go-inovation/mobile/mobile.go`](https://github.com/hajimehoshi/go-inovation/blob/master/mobile/mobile.go).
-
-```go
-package mobile
-
-import (
-        "github.com/hajimehoshi/ebiten/mobile"
-        "github.com/yourname/yourgame"
-)
-
-var (
-        running bool
-)
-
-const (
-        ScreenWidth  = 320
-        ScreenHeight = 240
-)
-
-// IsRunning returns a boolean value indicating whether the game is running.
-func IsRunning() bool {
-        return running
-}
-
-// Start starts the game.
-func Start(scale float64) error {
-        running = true
-        game, err := yourgame.NewGame()
-        if err != nil {
-                return err
-        }
-        // mobile.Start starts the game.
-        // In this function, scale is passed from Java side and pass it
-        // to mobile.Start. You can also receive the screen size from Java
-        // side by adding arguments to this function if you want to make
-        // Java side decide the screen size.
-        // Note that the screen size unit is dp (device-independent pixel).
-        if err := mobile.Start(game.Update, ScreenWidth, ScreenHeight, scale, "Your Game's Title"); err != nil {
-                return err
-        }
-        return nil
-}
-
-// Update proceeds the game.
-func Update() error {
-        return mobile.Update()
-}
-
-// UpdateTouchesOnAndroid dispatches touch events.
-func UpdateTouchesOnAndroid(action int, id int, x, y int) {
-        mobile.UpdateTouchesOnAndroid(action, id, x, y)
-}
-
-func UpdateTouchesOnIOS(phase int, ptr int64, x, y int) {
-        // Prepare this function if you also want to make your game run on iOS.
-        mobile.UpdateTouchesOnIOS(phase, ptr, x, y)
-}
-```
