 Typically, the various application module interfaces are implemented in a file called `module.go`, located in the module's folder (e.g. `./x/module/module.go`).
 
-Almost every module needs to implement the `AppModule` interfaces. If the module is only used for genesis, it will implement `AppModuleGenesis` instead of `AppModule`. The concrete type that implements the interface can add parameters that are required for the implementation of the various methods of the interface. For example, the `Route()` function often calls a `NewMsgServerImpl(k keeper)` function defined in `keeper/msg_server.go` and therefore needs to pass the module's [`keeper`](./06-keeper.md) as a parameter.
