 ## Built-in Middleware Examples
 
-FastMCP includes several production-ready middleware implementations that demonstrate best practices and provide immediately useful functionality. Let's explore how each type works by building simplified versions, then see how to use the full implementations.

 ### Timing Middleware
 
-Performance monitoring is essential for understanding your server's behavior and identifying bottlenecks. FastMCP includes production-ready timing middleware at `fastmcp.server.middleware.timing`.
