-Starter dimodifikasi dan terinspirasi dari:
-https://developer.android.com/codelabs/basic-android-compose-calculate-tip#0
+Introduction
+------------
+The Tip Time app contains various UI elements for calculating a tip,
+teaching about user input, and State in Compose.
+
+
+Pre-requisites
+--------------
+* Experience with Kotlin syntax.
+* How to create and run a project in Android Studio.
+
+
+Getting Started
+---------------
+1. Install Android Studio, if you don't already have it.
+2. Download the sample.
+3. Import the sample into Android Studio.
+4. Build and run the sample.
