 # CBDD
 
-CBDD is an embedded, document-oriented database engine for .NET 10. It targets internal platform teams that need predictable ACID behavior, low-latency local persistence, and typed access patterns without running an external database server.
+CBDD is an embedded, document-oriented database engine for .NET 10. It targets internal platform teams that need
+predictable ACID behavior, low-latency local persistence, and typed access patterns without running an external database
+server.
 
 ## Purpose And Business Context
 
-CBDD provides a local data layer for services and tools that need transactional durability, deterministic startup, and high-throughput reads/writes. The primary business outcome is reducing operational overhead for workloads that do not require a networked database cluster.
