+A Bill of Material ([BOM](https://maven.apache.org/guides/introduction/introduction-to-dependency-mechanism.html#bill-of-materials-bom-poms)) ensures that versions of dependencies (including transitive ones) are aligned.
+Importing the `opentelemetry-bom` BOM is important to ensure version alignment across all OpenTelemetry dependencies.
