 ## Code conventions
 
-- **Formatting**: google-java-format enforced via Spotless. Run `./gradlew spotlessApply` before committing.
+- **Formatting**: Prince of Space enforced via Spotless. Run `./gradlew spotlessApply` before committing.
 - **Static imports**: Prefer static imports over class-qualified calls for call-style helpers, in both test (Assertions.assertEquals, Mockito.mock) and production code (Collections.emptyList). Wildcard imports disallowed — see CONTRIBUTING.md.
 - **Documentation**: Use concise Javadoc comments (`/** ... */`) for class, method, and field documentation.
 - **Instrumentation layout**: `dd-java-agent/instrumentation/{framework}/{framework}-{minVersion}/`
