-## Managed resource definitions
-
-Crossplane v2 introduces Managed Resource Definitions (MRDs) that provide 
-selective resource activation and improved resource discovery.
-
-**MRDs solve performance and usability challenges with large providers.** 
-Installing a provider like AWS traditionally creates hundreds of CRDs, even if 
-you only need some resources. MRDs let you activate only the resources you 
-actually use.

-### Key managed resource definition benefits
-
-**Performance optimization** - Only create CRDs for resources you need, reducing 
-cluster overhead and improving provider installation speed.
-
-**Connection details discovery** - MRDs document what connection details each 
-managed resource provides, making it easier to understand resource capabilities.
-
-**Policy-based activation** - Use ManagedResourceActivationPolicy (MRAP) to 
-activate resources with flexible pattern matching.
-
-**safe-start providers** - Providers can opt into safe-start capability, starting 
-with all MRDs inactive for better performance.
