Just provisioned this with CDK, not sure how to update your documentation

[fusion27]

Wasn't sure how to issue you a README.md PR. Provisioned this with AWS CDK v2 using TypeScript

import * as cdk from 'aws-cdk-lib';
import { aws_sam, aws_iam } from 'aws-cdk-lib';

new aws_iam.Role(scope, `ServiceRoleNewRelicLogIngestionLambda`, {
  assumedBy: new aws_iam.ServicePrincipal(`lambda.amazonaws.com`),
  roleName: `NewRelicLogIngestionRole`,
  managedPolicies: [
    aws_iam.ManagedPolicy.fromAwsManagedPolicyName(`service-role/AWSLambdaBasicExecutionRole`),
  ],
})

const samApp:aws_sam.CfnApplication = new aws_sam.CfnApplication(scope,`LambdaNewRelicLogIngestion`, {
  location: {
    applicationId   : `arn:aws:serverlessrepo:us-east-1:463657938898:applications/NewRelic-log-ingestion`,
    semanticVersion : `2.6.4`
  },
  parameters: {
    `DebugLoggingEnabled`               : `False`,
    `FunctionRole`                      : `NewRelicLogIngestionRole`,
    `LogIngestionFunctionArnExportName` : 'LogIngestionFunctionArn',
    `MemorySize`                        : `128`,
    `NRInfraLogging`                    : `True`,
    `NRLicenseKey`                      : `1a2b3c4d5e6f7g8h9i10j11k12l13m14no15p16q`,
    `NRLoggingEnabled`                  : `True`,
    `Timeout`                           : `30`
  }
})
