+## Build
+
+### Linux
+
+`...`
+
+### Android
+
+**Подготовка Android окружения**.
+
+Необходимо выполнить следующие шаги:
+
+1. Установка модуля `vab` для **V**
+2. Установка **Android NDK**
+3. Установка **android-tools**
+4. Получение идентификатора устройства для деплоя
+
+**Установка модуля `vab` для V**
+
+```sh
+v install vab
+# Installed `vab` in ~/.vmodules/vab .
+vab install "platforms;android-33" # Silent output... wait!
+```
+
+**Получение идентификатора устройства**
+
+```sh
+adb devices -l
+```
