+## Architecture - MVVM
+`MVVM (Model-View-ViewModel) Architecture` combines the advantages of separation of concerns provided by MVP, while maintaining testability. This results in a pattern where the model drives as many of the operations as possible, minimizing the logic in the view.
+
+## Libraries Used
+
+### [Jetpack Libraries](https://developer.android.com/jetpack)
+Jetpack is a suite of libraries to help follow best practices, reduce boilerplate code, and write code that works consistently across Android versions and devices.
+
+### [Architecture Components](https://developer.android.com/topic/libraries/architecture)
+Android Architecture Components like `ViewModel`, `LiveData`and Lifecycle-aware components are implemented in this app for a more robust, testable and maintainable codebase.
+
+### [Dagger-Hilt](https://dagger.dev/hilt/)
+`Dagger-Hilt` is responsible for Dependency Injection throughout the app. It is used to inject dependencies like `Room` instance and `ViewModels`.
+
+### [Coroutines](https://kotlinlang.org/docs/coroutines-overview.html)
+`Coroutines` is used to execute code in an asynchronous and non-blocking way. It is heavily used in the `ViewModels` and also to make databse requests to the Room instance.
+
+### [Room](https://developer.android.com/jetpack/androidx/releases/room)
+`Room` persistence library provides an abstraction layer over SQLite to allow for more robust database access. It provides compile-time query verification, convenience annotations and less boilerplate code.
+
+### [Navigation Components](https://developer.android.com/guide/navigation)
+Navigation components is used to handle fragment transactions, and Up and Back actions correctly by default. It simplifies navigation and passing data between destinations in a type-safe way using `Safe Args`.
+
+### [View Binding](https://developer.android.com/topic/libraries/view-binding)
+View Binding is used to ensure compile-time safety for accessing the view hierarchy. It creates an instance of a binding class that contains direct references to all views that have an ID in the corresponding layout.
+
+### [Material Components](https://material.io/develop/android/)
+Material Components provide beautiful UI elements with a lots of customizations. It is used as it defines the latest standards for design by Google.
+
+### [Retrofit](https://github.com/square/retrofit)
+Retrofit with `Moshi` for JSON serialization/deserialization is used for networking in the app to make API calls to the SpaceX API.
+
+### [OkHttp Logging Interceptor](https://square.github.io/okhttp/)
+The OkHttp interceptor logs request and response information, and has been used to used to log all the body-level details related to the network calls for debugging purposes.
+
+### [Lottie Animations](https://github.com/airbnb/lottie-android/)
+Lottie is an amazing library for easy animations in Android, iOS and Web. The animations seen in this app represent some of the states of the app: Loading, Error or No Internet.
+
+### [Glide](https://github.com/bumptech/glide)
+Glide is the image library used in this app. It is fast and offers more fine-grained control over image loading.
+
+### [Timber Logging](https://github.com/JakeWharton/timber)
+`Timber` is a logger with a small, extensible API which provides utility on top of Android's normal Log class. It has been used for debugging purposes.
