+## Prerequisites

+- **Java Development Kit (JDK)**: JDK 17 or higher is required to build the project. JDK 25 is recommended.
+- **Gradle**: The project uses the Gradle Wrapper, so you do not need to install Gradle globally. Run command-line tasks
+  using `./gradlew` (or `gradlew.bat` on Windows).

 Shadow has multiple test suites to ensure code quality:
 
 - **Unit tests**: `./gradlew test`
-- **Documentation tests**: `./gradlew documentTest` - Tests code snippets in the `./docs` directory
+- **Documentation tests**: `./gradlew documentTest` - Tests code snippets in the `docs/` directory
 - **Functional/Integration tests**: `./gradlew functionalTest`
 
+#### Running Specific Tests
+
+To speed up local development, you can run specific test classes or methods:
+
+- Run a specific unit test: `./gradlew test --tests "com.example.YourTestClass"`
+- Run functional tests against a specific Gradle version: `./gradlew functionalTest -PtestGradleVersion=9.1.0` (useful
+  to verify compatibility locally with the minimum or a custom Gradle version)
+
 Make sure all tests pass before submitting your changes.
 
 ### API Compatibility
 
-Shadow uses Kotlin's [binary compatibility validator](https://kotlinlang.org/docs/gradle-binary-compatibility-validation.html) to track public API changes.
+Shadow uses Kotlin's built-in ABI validator to track public API changes.
 
 - **Check API dumps**: `./gradlew checkKotlinAbi`
 - **Update API dumps**: `./gradlew updateKotlinAbi`
 
-If you add or modify public APIs, you'll need to update the API dump files.
+API dump files are located under the `api/` directory (e.g., [shadow.api](api/shadow.api)). If you add or modify public
+APIs, you'll need to run `./gradlew updateKotlinAbi` to update the API dump files and include the updated dump files in
