-Cicerone (a guide, one who conducts sightseers) is a lightweight library that makes the navigation in an Android app easy.  
-It was designed to be used with the MVP pattern (try [Moxy](https://github.com/Arello-Mobile/Moxy)), but will work great with any architecture.
+Cicerone (means - a guide, one who conducts sightseers) is a lightweight library that makes the navigation in an Android app easy.  
+It was designed to be used with the MVP/MVVM/MVI patterns but will work great with any architecture.

 ## Main advantages
 + is not tied to Fragments
-+ not a framework
+ not a framework (very lightweight)
 + short navigation calls (no builders)
+ static typed checks for screen parameters!
 + lifecycle-safe!
 + functionality is simple to extend
 + suitable for Unit Testing

 ## Additional features
-+ easy screen result subscription
+ opening several screens inside single call (for example: deeplink)
+ provides `FragmentFactory` if it needed
+ `add` or `replace` strategy for opening next screen (see `router.navigateTo` last parameter)
+ implementation of parallel navigation (Instagram like)
+ predefined navigator ready for Single-Activity apps
 + predefined navigator ready for setup transition animation
-**See the sample application**

 ## How to add
 Add the dependency in your build.gradle:
-```groovy
+```kotlin
 dependencies {
    //Cicerone
-    compile 'ru.terrakok.cicerone:cicerone:X.X.X'
+    implementation("com.github.terrakok:cicerone:X.X.X")
 }
 ```

 Initialize the library (for example in your Application class):
-```java
-public class SampleApplication extends MvpApplication {
-    public static SampleApplication INSTANCE;
-    private Cicerone<Router> cicerone;
+```kotlin
+class App : Application() {
+    private val cicerone = Cicerone.create()
+    val router get() = cicerone.router
+    val navigatorHolder get() = cicerone.getNavigatorHolder()

-    @Override
-    public void onCreate() {
-        super.onCreate();
-        INSTANCE = this;
-
-        initCicerone();
+    override fun onCreate() {
+        super.onCreate()
+        INSTANCE = this
    }

-    private void initCicerone() {
-        cicerone = Cicerone.create();
-    }
-
-    public NavigatorHolder getNavigatorHolder() {
-        return cicerone.getNavigatorHolder();
-    }
-
-    public Router getRouter() {
-        return cicerone.getRouter();
+    companion object {
+        internal lateinit var INSTANCE: App
+            private set
    }
 }
 ```

 Presenter calls navigation method of Router.

-    public SamplePresenter() {
-        router = SampleApplication.INSTANCE.getRouter();
+    fun onOpenNewScreen() {
+        router.navigateTo(SomeScreen())
    }

-    public void onBackCommandClick() {
-        router.exit();
-    }
-
-    public void onForwardCommandClick() {
-        router.navigateTo("Some screen");
+    fun onBackPressed() {
+        router.exit()
    }
 }
 ```

-## Predefined navigators
-The library provides predefined navigators for _Fragments_ to use inside _Activity_.
-To use, just provide it with the container and _FragmentManager_ and override few simple methods.
-```java
-private Navigator navigator = new SupportAppNavigator(this, R.id.container) {
-    @Override
-    protected Intent createActivityIntent(Context context, String screenKey, Object data) {
-        return null;
-    }
-
-    @Override
-    protected Fragment createFragment(String screenKey, Object data) {
-        switch (screenKey) {
-            case Screens.PROFILE_SCREEN:
-                return new ProfileFragment();
-            case Screens.SELECT_PHOTO_SCREEN:
-                return SelectPhotoFragment.getNewInstance((int) data);
-        }
-        return null;
-    }
-
-    @Override
-    protected void setupFragmentTransactionAnimation(
-                Command command,
-                Fragment currentFragment,
-                Fragment nextFragment,
-                FragmentTransaction fragmentTransaction) {
-        //setup animation
-    }
-};
+## Predefined navigator
+The library provides predefined navigator for _Fragments_ and _Activity_.
+To use, just provide it with the container and _FragmentManager_.
+```kotlin
+private val navigator = AppNavigator(this, R.id.container)
 ```
-## Sample
-To see how to add, initialize and use the library and predefined navigators check out the sample.

-![](https://habrastorage.org/web/a63/881/7f8/a638817f8bba49daacc4fa427987fabb.gif)
+Custom navigator can be useful sometimes:
+```kotlin
+private val navigator = object : AppNavigator(this, R.id.container) {
+    override fun setupFragmentTransaction(
+        fragmentTransaction: FragmentTransaction,
+        currentFragment: Fragment?,
+        nextFragment: Fragment?
+    ) {
+        super.setupFragmentTransaction(fragmentTransaction, currentFragment, nextFragment)
+        fragmentTransaction.setReorderingAllowed(true)
+    }
+
+    override fun applyCommands(commands: Array<out Command>) {
+        hideKeyboard()
+        super.applyCommands(commands)
+    }
+}
+```
+
+## Screens
+Describe your screens as you like e.g. create Kotlin `object` with all application screens:
+```kotlin
+object Screens {
+    fun Main() = FragmentScreen { MainFragment() }
+    fun AddressSearch() = FragmentScreen { AddressSearchFragment() }
+    fun Profile(userId: Long) = FragmentScreen("Profile_$userId") { ProfileFragment(userId) }
+    fun Browser(url: String) = ActivityScreen { Intent(Intent.ACTION_VIEW, Uri.parse(url))  }
+}
+```
+
+Additional you can use `FragmentFactory` for creating your screens:
+```kotlin
+fun SomeScreen() = FragmentScreen { factory: FragmentFactory -> ... }
+```
+
+## Screen parameters and result listener
+```kotlin
+//you have to specify screen parameters via new FragmentScreen creation
+fun SelectPhoto(resultKey: String) = FragmentScreen {
+    SelectPhotoFragment.getNewInstance(resultKey)
+}
+```
+
+```kotlin
+//listen result
+fun onSelectPhotoClicked() {
+    router.setResultListener(RESULT_KEY) { data ->
+        view.showPhoto(data as Bitmap)
+    }
+    router.navigateTo(SelectPhoto(RESULT_KEY))
+}
+
+//send result
+fun onPhotoClick(photo: Bitmap) {
+    router.sendResult(resultKey, photoRes)
+    router.exit()
+}
+```

-Cicerone (_"чи-че-ро́-не"_ - устар. гид) - легкая библиотека для простой реализации навигации в андроид приложении.  
-Разработана для использования в MVP архитектуре (попробуйте [Moxy](https://github.com/Arello-Mobile/Moxy)), но легко встраивается в любые решения.
-
-## Основные преимущества
-+ не завязана на Fragment'ы
-+ не фреймворк
-+ короткие вызовы навигации (никаких билдеров)
-+ lifecycle-безопасна!
-+ простое расширение функционала
-+ приспособлена для Unit тестов
-
-## Как подключить?
-Добавьте в build.gradle зависимость:
-```groovy
-dependencies {
-    //Cicerone
-    compile 'ru.terrakok.cicerone:cicerone:X.X.X'
-}
-```
-И инициализируйте библиотеку, например, так:
-```java
-public class SampleApplication extends MvpApplication {
-    public static SampleApplication INSTANCE;
-    private Cicerone<Router> cicerone;
-
-    @Override
-    public void onCreate() {
-        super.onCreate();
-        INSTANCE = this;
-
-        initCicerone();
-    }
-
-    private void initCicerone() {
-        cicerone = Cicerone.create();
-    }
-
-    public NavigatorHolder getNavigatorHolder() {
-        return cicerone.getNavigatorHolder();
-    }
-
-    public Router getRouter() {
-        return cicerone.getRouter();
-    }
-}
-```
-
-## Как это работает?
-![](https://habrastorage.org/files/4df/45d/973/4df45d9733fc4ee0a2f0be933de475b1.png)
-
-Presenter вызывает у Router метод навигации.
-
-```java
-public class SamplePresenter extends Presenter<SampleView> {
-    private Router router;
-
-    public SamplePresenter() {
-        router = SampleApplication.INSTANCE.getRouter();
-    }
-
-    public void onBackCommandClick() {
-        router.exit();
-    }
-
-    public void onForwardCommandClick() {
-        router.navigateTo("Some screen");
-    }
-}
-```
-
-Router - класс, который реализует вызванный метод навигации набором Command и отправляет их в CommandBuffer.
-CommandBuffer проверяет есть ли _"активный"_ Navigator.
-Если да, то на нем вызываются необходимые команды для осуществления запрошенного перехода.
-Если нет, то команды добавляются в очередь, которая будет применена, как только появится _"активный"_ Navigator.
-
-```java
-protected void executeCommand(Command command) {
-    if (navigator != null) {
-        navigator.applyCommand(command);
-    } else {
-        pendingCommands.add(command);
-    }
-}
-```
-
-Navigator - (например) анонимный класс внутри Activity, который реализует команды навигации.
-Activity предоставляет свой Navigator для CommandBuffer в методе _onResume_ и очищает в _onPause_
-
-**Внимание**: В FragmentActivity следует использовать _onResumeFragments()_. ([подробнее](https://developer.android.com/reference/android/support/v4/app/FragmentActivity.html#onResume()))
-
-```java
-@Override
-protected void onResume() {
-    super.onResume();
-    SampleApplication.INSTANCE.getNavigatorHolder().setNavigator(navigator);
-}
-
-@Override
-protected void onPause() {
-    super.onPause();
-    SampleApplication.INSTANCE.getNavigatorHolder().removeNavigator();
-}
-
-private Navigator navigator = new Navigator() {
-    @Override
-    public void applyCommand(Command command) {
-        //implements commands logic
-    }
-};
-```
-
-Навигатор не обязан быть в Activity. Он может быть и внутри Fragment'а, который переключает внутри себя View.
-
-## Команды навигатора
-Для большинства задач предоставленных в библиотеке команд должно хватить, но их всегда можно дополнить собственными!
-+ Forward - переход на новый экран  
-![](https://habrastorage.org/files/862/77e/b20/86277eb20b574dae8307ac4f64b0f090.png)
-+ Back - возврат на предыдущий экран  
-![](https://habrastorage.org/files/059/b63/2d3/059b632d3a7c4515a534b9e5e881c8f0.png)
-+ BackTo - возврат к конкретному экрану в цепочке, либо на корневой, если указанный экран не найден  
-![](https://habrastorage.org/files/a45/4f4/c34/a454f4c340764632ad0669014ad5550d.png)

-![](https://habrastorage.org/files/4ae/95c/fee/4ae95cfee4c04f038ad17d358ab08d07.png)
-+ SystemMessage - показ системного сообщения (Alert, Toast, Snack и тд)  
-![](https://habrastorage.org/files/6e7/1a6/4ed/6e71a64edec04079bf33faa7ab39606f.png)
-
-## Готовые навигаторы
-Библиотека предоставляет готовые навигаторы для _Activity_.
-Чтобы их использовать, достаточно указать контейнер и передать _FragmentManager_.
-```java
-private Navigator navigator = new SupportFragmentNavigator(
-                              getSupportFragmentManager(), R.id.main_container) {
-    @Override
-    protected Fragment createFragment(String screenKey, Object data) {
-        return SampleFragment.getNewInstance((int) data);
-    }
-
-    @Override
-    protected void showSystemMessage(String message) {
-        Toast.makeText(MainActivity.this, message, Toast.LENGTH_SHORT).show();
-    }
-
-    @Override
-    protected void exit() {
-        finish();
-    }
-};
-```
