 AWS offers several tools to interact and deploy Lambda functions to AWS Lambda including [SAM](https://aws.amazon.com/serverless/sam/) and the [AWS CLI](https://aws.amazon.com/cli/). The [Examples Directory](/Examples) includes complete sample build and deployment scripts that utilize these tools.
 
-Note the examples mentioned above use dynamic linking, therefore bundle the required Swift libraries in the Zip package along side the executable. You may choose to link the Lambda function statically (using `-static-stdlib`) which could improve performance but requires addition linker flags.

 To build the Lambda function for Amazon Linux, use the Docker image published by Swift.org on [Swift toolchains and Docker images for Amazon Linux 2](https://swift.org/download/), as demonstrated in the examples.
