+### Общее описание
+
+Модуль содержит: 
+`ViewableAlertDialog` - служит для демонстрации AlertDialog с использованием View, необходимо вызвать метод `showAlertDialog`, который 
+в качестве агруметов может принимать:
+* title - Заголовок диалога
+* message - дополнительное сообщение
+* positiveButtonText - текст правой кнопки (по умолчанию "ОК") 
+* onPositiveAction - колбэк при нажатии на правую кнопку
+* negativeBtnTitle - текст левой кнопки (по умолчаннию null - в этом случаи не отображается)
+* onNegativeAction - колбэк при нажатии на левую кнопку,
+* dialogLayout - id кастомного layout (по умолчанию R.layout.dialog_alert)
+
+---
+`ComposableAlertDialog` - служит для демонстрации AlertDialog с использованием Jetpack Compose, необходимо вызвать метод `ShowAlertDialog`, который 
+в качестве агруметов может принимать:
+* isDialogOpen - индикатор состояния диалога
+* title - Заголовок диалога
+* message - дополнительное сообщение
+* positiveButtonText - текст правой кнопки
+* onPositiveAction - колбэк при нажатии на правую кнопку
+* negativeBtnTitle - текст левой кнопки (по умолчаннию null - в этом случаи не отображается)
+* onNegativeAction - колбэк при нажатии на левую кнопку,
+
+Кастомизация Compose версии происходит по средствам инициализации полей: customTitle, customMessage, customConfirmBtn, customNegativeBtn
+
+### Примеры
+
+View версия (ViewableAlertDialog):
+```kotlin
+ViewableAlertDialog.showAlertDialog(
+                activity,
+                title = "Ой, что-то пошло не так",
+                message = "Попробуйте ещё раз",
+                positiveButtonText = "Ещё раз",
+                onPositiveAction = { retryConnection() }, 
+                negativeBtnTitle = "Отмена"
+            )
+```
+
+Compose версия (ComposableAlertDialog):
+```kotlin
+val isDialogOpen = remember { mutableStateOf(false)}
+....
+//Создание диалога
+ComposableAlertDialog
+            .apply { customTitle = { Text(text = "Ой, что-то пошло не так", color = Color.Blue) } }
+            .ShowAlertDialog(isDialogOpen, message = "Проблемы с сетью", positiveButtonText = "ОК")
+....
+//Отображение диалога
+isDialogOpen.value = true
+```
