+### Function Example
+You can use this template as a sample for a simple function of your application.
+Context will be mapped from `lambda-context` attribute of the request as stated [here](https://bref.sh/docs/use-cases/http/advanced-use-cases#lambda-event-and-context). 
+
+This function is giving the output as per [Lambda Proxy Integration Response spec](https://docs.aws.amazon.com/apigateway/latest/developerguide/set-up-lambda-proxy-integrations.html#api-gateway-simple-proxy-for-lambda-output-format)
