+# Building Compose Samples
+
+This repository contains multiple Android sample projects demonstrating Jetpack Compose.
+
+## Repository Structure
+
+The repository is organized as a Gradle multi-project build with the following structure:
+
+- Each sample (JetNews, Jetchat, Jetsnack, Jetcaster, Reply, JetLagged) is an independent Android project
+- Root-level Gradle configuration provides convenience tasks to build all samples
+
+## Building All Samples
+
+From the root directory, you can use the following commands:
+
+### Build all samples
+```bash
+./gradlew build
+```
+
+### Assemble debug builds
+```bash
+./gradlew assembleDebug
+```
+
+### Clean all samples
+```bash
+./gradlew clean
+```
+
+### Run tests
+```bash
+./gradlew test
+```
+
+### Check code formatting
+```bash
+./gradlew spotlessCheck
+```
+
+### Apply code formatting
+```bash
+./gradlew spotlessApply
+```
+
+## Building Individual Samples
+
+You can also build samples individually by navigating to their directory:
+
+```bash
+cd JetNews
+./gradlew assembleDebug
+```
+
+## Using Recursive Scripts
+
+The repository also includes shell scripts in the `scripts/` directory for running commands across all samples:
+
+```bash
+./scripts/gradlew_recursive.sh build
+./scripts/format.sh
+./scripts/verify_samples.sh
+```
+
+## Requirements
+
+- JDK 17 or higher
+- Android SDK
+- Gradle 8.13+ (wrapper included)
+
+For more information about individual samples, see their respective README files.
