text: **How to process events with a Lambda handler**
  
  Conceptually, there are only three steps to processing events with Lambda: 
  
  1. Conﬁgure the entry point to your function, known as the*handler*, and deploy the function. 
  
  2. Lambda service initializes the function, then it invokes the*handler*with an invocation event and 
  
  context. 
  
  3. Your handler function processes the event and returns a response event.
