 ## OpenTelemetry Lambda Layers
 
-The OpenTelemetry Lambda Layers provide the OpenTelemetry (OTel) code to export telemetry asynchronously from AWS Lambdas. It does this by embedding a stripped-down version of [OpenTelemetry Collector Contrib](https://github.com/open-telemetry/opentelemetry-collector-contrib) inside an [AWS Lambda Extension Layer](https://aws.amazon.com/blogs/compute/introducing-aws-lambda-extensions-in-preview/).

 ### Custom context propagation carrier extraction
 
-Context can be propagated through various mechanisms (e.g. http headers (APIGW), message attributes (SQS), ...). In some cases, it may be required to pass a custom context propagation extractor in lambda through configuration, this feature allows this through Lambda instrumentation configuration.
