-#### 2.3 Test Application
-You can see how MobileFFmpeg is used inside an application by running test applications provided.
-There is an Android test application under the `android/test-app` folder and an IOS test application, which requires 
-`Xcode 9.x` or later, under the `ios/test-app` folder. Both applications are identical and supports command 
-execution, video encoding, accessing https, encoding audio, burning subtitles and video stabilization.

+#### 2.3 Manual Installation
+##### 2.3.1 Android
+
+You can import `MobileFFmpeg` aar packages in `Android Studio` using the `File` -> `New` -> `New Module` -> `Import .JAR/.AAR Package` menu.
+
+##### 2.3.2 iOS / tvOS
+
+iOS and tvOS frameworks can be installed manually using the [Importing Frameworks](https://github.com/tanersener/mobile-ffmpeg/wiki/Importing-Frameworks) guide. 
+If you want to use universal binaries please refer to [Using Universal Binaries](https://github.com/tanersener/mobile-ffmpeg/wiki/Using-Universal-Binaries) guide.

 ### 3. Versions
 
-- `MobileFFmpeg v1.x` is the previous stable, includes `FFmpeg v3.4.4`
+`MobileFFmpeg` version number is aligned with `FFmpeg` since version `4.2`. 
 
-- `MobileFFmpeg v2.x` is the current stable, includes `FFmpeg v4.0.2`
+In previous versions, `MobileFFmpeg` version of a release and `FFmpeg` version included in that release was different. 
+The following table lists `FFmpeg` versions used in `MobileFFmpeg` releases.
+  
+- `dev` part in `FFmpeg` version number indicates that `FFmpeg` source is pulled from the `FFmpeg` `master` branch. 
+Exact version number is obtained using `git describe --tags`.

+### 4. LTS Releases
+
+Starting from `v4.2`, `MobileFFmpeg` binaries are published in two different variants: `Main Release` and `LTS Release`. 
+
+- Main releases include complete functionality of the library and support the latest SDK/API features.
+
+- LTS releases are customized to support a wider range of devices. They are built using older API/SDK versions, so some features are not available on them.
+
+This table shows the differences between two variants.
