# ZoneTree Docs

ZoneTree is a high-performance LSM-tree storage engine for .NET. It provides ordered, persistent key-value storage that can be used directly or as the foundation for databases, indexes, queues, search systems, event stores, and custom data platforms.

These docs explain the mental model behind ZoneTree, the main APIs, and the operational choices that matter in production.
