This is the central governance and documentation repository for the Jackson project, the premier Java JSON processing library. It does not contain the core library source code (which lives in separate repos like `jackson-core`, `jackson-databind`, and `jackson-annotations`). Instead, it serves as the project's hub, containing all essential governance documents (CLAs, contributing guidelines, security policy, versioning strategy), a comprehensive API reference manual (`MANUAL.md`), and an exceptionally detailed migration guide from Jackson 2.x to 3.x. The repository is a masterclass in open-source project management and technical documentation, providing a clear, well-structured, and authoritative source of truth for the entire Jackson ecosystem. Its primary value lies not in executable code, but in the high-quality, reusable patterns it establishes for project governance, release engineering, and technical communication.
