 ## Basic Usage
 
+Datadog needs to be able to read headers from the incoming Lambda event. To do this, you must wrap your handler function with our library. We provide some easy ways of wrapping your handlers.
+
+### Redirected Handler
+
+We provide a swap in replacement handler, with zero required code changes.
+
+1. Set the environment variable `DD_LAMBDA_HANDLER` to your regular handler location, eg. `myfunc.handler`.
+2. Set your handler to `datadog_lambda.handler.handler`.
+
+### Manual Wrap
+
+You might find it more convenient to wrap your handlers manually.

 ```python
 import requests
 from datadog_lambda.wrapper import datadog_lambda_wrapper
