 # Core
 
-Core is package which specifies the interfaces for core components of the Cosmos SDK.  Other packages in the SDK implement these interfaces to provide the core functionality.  This design provides modularity and flexibility to the SDK, allowing developers to swap out implementations of core components as needed.  As such it is often referred to as the Core API.

 ## Environment
 
-The `Environment` struct is a core component of the Cosmos SDK.  It provides access to the core services of the SDK, such as the KVStore, EventManager, and Logger.  The `Environment` struct is passed to modules and other components of the SDK to provide access to these services.

 ## Event Service
 
 The Event Service returns a handle to an [EventManager](https://pkg.go.dev/cosmossdk.io/core@v1.0.0-alpha.4/event#Manager)
