-Kalkulator BMI
-===============
-Langkah-langkah:
+Tip Time - Solution Code
+=================================
 
-1. Clone Repository Project
-Saya meng-clone repository project dari GitHub menggunakan Android Studio untuk dijadikan dasar pengerjaan tugas.
+Solution code for the [Android Basics with Compose](https://developer.android.com/courses/android-basics-compose/course): Tip Time app.
 
-2. Modifikasi Tampilan Aplikasi
-Saya meminta bantuan ChatGPT dan DeepSeek untuk memberikan saran tampilan aplikasi agar lebih menarik. Setelah itu, saya menyesuaikan tampilan sesuai arahan yang diberikan.
 
-3. Mengubah Icon Aplikasi (APK)
-Saya mengganti icon aplikasi melalui fitur Image Asset di Android Studio dengan icon baru sesuai arahan dari ChatGPT.
+Introduction
+------------
+The Tip Time app contains various UI elements for calculating a tip,
+teaching about user input, and State in Compose.
 
-4. Review dan Uji Coba
-Setelah perubahan selesai, saya menjalankan aplikasi untuk memastikan tampilan dan icon sudah berubah dengan baik.
 
-Petunjuk lebih detil dapat dibaca di
-https://docs.google.com/document/d/1iGiC0Bg3Bdcd2Maq45TYkCDUkZ5Ql51E/edit?rtpof=true
+Pre-requisites
+--------------
+* Experience with Kotlin syntax.
+* How to create and run a project in Android Studio.
 
-Starter dimodifikasi dan terinspirasi dari:
-https://developer.android.com/codelabs/basic-android-compose-calculate-tip#0
+
+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.
