 ## Lambda layers used
 1. An auto instrumentation lambda [layer](https://github.com/open-telemetry/opentelemetry-lambda/releases/tag/layer-nodejs%2F0.4.0) for Nodejs. Read more [here](https://opentelemetry.io/docs/faas/lambda-auto-instrument/)
-2. An Opentelemetry Collector [layer](https://github.com/open-telemetry/opentelemetry-lambda/releases/tag/layer-collector%2F0.4.0). Read more [here](https://opentelemetry.io/docs/faas/lambda-collector/)
+2. <em>(Optional)</em> An Opentelemetry Collector [layer](https://github.com/open-telemetry/opentelemetry-lambda/releases/tag/layer-collector%2F0.4.0). Read more [here](https://opentelemetry.io/docs/faas/lambda-collector/)
 
 Note: Since the auto-instrumentation layer does not have support for logs yet, an instrumentation file is provided that adds the required libraries to collect and export logs.
