  +### Setting a Dead Letter Queue
  +
  +```js
  +const queue = new sst.Queue(this, "MyDLQ");
  +new sst.Function(this, "MyApiLambda", {
  + handler: "src/api.main",
  + deadLetterQueue: queue.sqsQueue,
  +});
  +```
  +
  +### Setting SSM vales as environment variables
  +
  +```js
  +import * as ssm from "@aws-cdk/aws-ssm";
  +import * as sst from "@serverless-stack/resources";
  +const apiKey = ssm.StringParameter.valueFromLookup(this, "my_api_key");
  +new sst.Function(this, "MyApiLambda", {
  + handler: "src/api.main",
  + environment: {
  + API_KEY: apiKey,
  + },
  +});
  +```
  +
  +The `API_KEY` environment variable can be accessed as `process.env.API_KEY` within the Lambda function.
