 ## 📥 Build and Development (Android Studio)

 ### Requirements

- Latest version of Android Studio
- Components updated to the latest versions
+- Latest Android Studio
+- JDK from Android Studio (JetBrains Runtime)

-### Quick Start
+### Quick start

 1. **Clone the repository:**
-  ```bash
-   git clone https://github.com/fromchat-messenger/app.git
-   cd app
-  ```
+
+   ```bash
+   git clone https://github.com/fromchat-messenger/android.git

 ## 📥 Сборка и разработка (Android Studio)

 ### Требования

- Последняя версия Android Studio
- Компоненты, обновленные до последних версий
+- Актуальная Android Studio
+- JDK из Android Studio (JetBrains Runtime)

 ### Быстрый старт

 1. **Клонируйте репозиторий:**
-  ```bash
-   git clone https://github.com/fromchat-messenger/app.git
-   cd app
-  ```
+
+   ```bash
+   git clone https://github.com/fromchat-messenger/android.git
+   cd android
+   ```
+
 2. **Сгенерируйте ключи (Debug & Release):**
-  1. Установите переменные (замените `CHANGEME` на ваши надежные пароли):
-    ```bash
-    DEBUG_STORE_PASS=CHANGEME
-    DEBUG_KEY_PASS=CHANGEME
-    RELEASE_STORE_PASS=CHANGEME
-    RELEASE_KEY_PASS=CHANGEME
-    ```
-  2. Выполните команды:
-    ```bash
-    mkdir -p app/android/keys

-    keytool -genkey -v -keystore app/android/keys/debug.jks \
-      -keyalg RSA -keysize 2048 -validity 10000 \
-      -alias key0 -storepass $DEBUG_STORE_PASS -keypass $DEBUG_KEY_PASS \
-      -dname "CN=Debug, O=FromChat, C=RU"
+   ```bash
+   DEBUG_STORE_PASS=CHANGEME
+   DEBUG_KEY_PASS=CHANGEME
+   RELEASE_STORE_PASS=CHANGEME
+   RELEASE_KEY_PASS=CHANGEME

-    keytool -genkey -v -keystore app/android/keys/release.jks \
-      -keyalg RSA -keysize 2048 -validity 10000 \
-      -alias key0 -storepass $RELEASE_STORE_PASS -keypass $RELEASE_KEY_PASS \
-      -dname "CN=Release, O=FromChat, C=RU"
+   mkdir -p app/android/keys

-    cat > app/android/keystore.properties << EOF
-    releaseStorePassword=$RELEASE_STORE_PASS
-    releaseKeyPassword=$RELEASE_KEY_PASS
-    debugStorePassword=$DEBUG_STORE_PASS
-    debugKeyPassword=$DEBUG_KEY_PASS
-    EOF
-    ```
-3. **Откройте в Android Studio:**
-  - Выберите: `File → Open → app/`
-  - Android Studio автоматически загружает все зависимости и синхронизирует Gradle
-4. **Запустите:**
-  - Нажмите `Run → Run 'Android'` (Shift+F10)
-  - Выберите эмулятор или подключённое устройство
+   keytool -genkey -v -keystore app/android/keys/debug.jks \
+     -keyalg RSA -keysize 2048 -validity 10000 \
+     -alias key0 -storepass $DEBUG_STORE_PASS -keypass $DEBUG_KEY_PASS \
+     -dname "CN=Debug, O=FromChat, C=RU"
+
+   keytool -genkey -v -keystore app/android/keys/release.jks \
+     -keyalg RSA -keysize 2048 -validity 10000 \
+     -alias key0 -storepass $RELEASE_STORE_PASS -keypass $RELEASE_KEY_PASS \
+     -dname "CN=Release, O=FromChat, C=RU"
+
+   cat > app/android/keystore.properties << EOF
+   releaseStorePassword=$RELEASE_STORE_PASS
+   releaseKeyPassword=$RELEASE_KEY_PASS
+   debugStorePassword=$DEBUG_STORE_PASS
+   debugKeyPassword=$DEBUG_KEY_PASS
+   EOF
+   ```
+
+3. **Откройте в Android Studio:** `File → Open` → корень репозитория. Gradle подтянет зависимости сам.
+
+4. **Запустите:** `Run → Run 'Android'` (или debug-конфигурацию приложения).  
+   Debug application id: `ru.fromchat.beta`.
+
+### Сборка из CLI
