+## About The Project
+The **nest-lambda-microservice** library enables you implement AWS Lambda functions using [NestJS](https://docs.nestjs.com/) framework in a microservice architectural style.
+This library fills the void, of not being able to run HTTP-style applications on AWS Lambda, with the ability to run RPC-style application using [NestJS microservice](https://docs.nestjs.com/microservices/basics).
+
+How it works in a nutshell:
+1. Creates an instance of NestJS application outside the AWS Lambda handler and cache it for as long as the Lambda execution environment is up.
+2. Emit the events received by the Lambda instance to the NestJS application via the event broker.
+3. The NestJS application uses qualification criteria to identify which handler (controller method) qualifies the request and sends it for processing.
+4. Once the handler processed the request and returned a response, the response is mapped or ignored based on the Lambda event source.
