+# View Binding
+
+Android sample app to learn about view binding in Android. It mainly showcases:
+- Enabling view binding through the app's build file.
+- Setting up binding instances in activities.
+- Setting up binding instances in Fragments using both the `inflate(LayoutInflater)` and `bind(View)` static methods.
+- Accessing and interacting with views through the binding instances.
+- Setting up layout files differently for different configurations, and accessing them through the binding instances with their nullable references.

+
+### Resources to learn about view binding
+- [The official documentation on View Binding](https://developer.android.com/topic/libraries/view-binding)
