 The stream decoding and rendering is demanded to [VLC's library](https://code.videolan.org/videolan/vlc-android): without their effort this app wouldn't be possible.
 This app was specifically developed for F-Droid, as I couldn't find any open source RTSP vievers in the main repository.
 
+The app can be opened deeplinking to url ojo://view.
+To open the app with focus on a specific camera, you can use an intent (it.danieleverducci.ojo.OPEN_CAMERA) to specify which camera you want to view.
+The extra argument it.danieleverducci.ojo.CAMERA_NAME will open the app with the camera with the name you specified while adding the camera.
+The extra argument it.danieleverducci.ojo.CAMERA_NUMBER starting at 1 could be used as well, if you have multiple cameras with the same name.
+See belows example how to use the intent. The flag (-f 268468224) could be useful if you want to switch to an other camera while the app is running.
+```shell
+adb -s <YOUR_DEVICE> shell am start -a it.danieleverducci.ojo.OPEN_CAMERA -f 268468224 --es it.danieleverducci.ojo.CAMERA_NAME <YOUR_CAMERA_NAME>
+adb -s <YOUR_DEVICE> shell am start -a it.danieleverducci.ojo.OPEN_CAMERA -f 268468224 --es it.danieleverducci.ojo.CAMERA_NUMBER <YOUR_CAMERA_NUMBER>

 Ojo is a basic IP Camera surveillance wall.

 The maximum number of cameras is determined by the device's capabilities.
 
 The stream decoding and rendering is demanded to VLC's library: without their effort this app wouldn't be possible.

+This app was specifically developed for F-Droid, as I couldn't find any open source RTSP viewers in the main repository.
+
+The app can be opened deeplinking to url ojo://view
+To open the app with focus on a specific camera, you can use an intent (it.danieleverducci.ojo.OPEN_CAMERA) to specify which camera you want to view.
+The extra argument it.danieleverducci.ojo.CAMERA_NAME will open the app with the camera with the name you specified while adding the camera.
+The extra argument it.danieleverducci.ojo.CAMERA_NUMBER starting at 1 could be used as well, if you have multiple cameras with the same name.
+
+See below an example how to use the intent. The flag (-f 268468224) could be useful if you want to switch to another camera while the app is running:
+
+    adb -s <YOUR_DEVICE> shell am start -a it.danieleverducci.ojo.OPEN_CAMERA -f 268468224 --es it.danieleverducci.ojo.CAMERA_NAME <YOUR_CAMERA_NAME>

+OJO это базовый просмотрщик IP камер наблюдения.
+RTSP потоки IP камеры добавляются через его URL адрес и показаны в классической плиточной конфигурации. Количество плиток автоматически выбирается на основе количества настроенных камер: одна камера показана на весь экран, добавление больше камер переключает на сетку: 2x2, 3x3, 4x4 и т. д.
+
+Максимальное количество камер определяется возможностями устройства.
+
+Декодирование и рендеринг потока требует библиотеки VLC: без их стараний это приложение не было бы возможно.
+
+Это приложение было специально разработано для F-Droid, так как я не мог найти каких-либо просмотрщиков RTSP с открытым исходным кодом в основном репозитории.
+
+Приложение может быть открыто с глубокой ссылкой по URL ojo://view.
+Чтобы открыть приложение с фокусом на определенной камере, вы можете использовать intent (it.danieleverducci.ojo.OPEN_CAMERA) чтобы указать какую камеру вы хотите просмотреть.
+Дополнительный аргумент it.danieleverducci.ojo.CAMERA_NAME откроет приложение с камерой с указанным вами названием при добавлении камеры.
+Дополнительный аргумент it.danieleverducci.ojo.CAMERA_NUMBER начиная с 1 также может использоваться, если у вас есть несколько камер с одним и тем же названием.
+
+Ниже пример как использовать intent. Флаг (-F 268468224) может быть полезен, если вы хотите переключиться на другую камеру во время работы приложения:
+
+    adb -s <ВАШЕ_УСТРОЙСТВО> shell am start -a it.danieleverducci.ojo.OPEN_CAMERA -f 268468224 --es it.danieleverducci.ojo.CAMERA_NAME <ИМЯ_ВАШЕЙ_КАМЕРЫ>
