 ### Architecture Guidelines
 
 - Use `LightningNodeService` to manage background notifications while the node is running
 - Use `LightningService` to wrap node's RUST APIs and manage the inner lifecycle of the node
 - Use `LightningRepo` to defining the business logic for the node operations, usually delegating to `LightningService`
 - Use `WakeNodeWorker` to manage the handling of remote notifications received via cloud messages
+- Use `*Services` to wrap rust library code exposed via bindings
+- Use CQRS pattern of Command + Handler like it's done in the `NotifyPaymentReceived` + `NotifyPaymentReceivedHandler` setup
