+# Amazon Lambda function code examples in Go
+
+This code example uses the 
+[AWS Cloud Development Kit (AWS CDK)](https://docs.aws.amazon.com/cdk/latest/guide/home.html) 
+to create the following resources:
+
+- An Amazon S3 bucket
+- An Amazon DynamoDB table
+- An Amazon SNS topic
+- An Amazon SQS queue
+
+In addition, this project creates AWS Lambda functions,
+in Go, to detect the following events:
+
+- An object uploaded to the Amazon S3 bucket
+- An item added to the Amazon DynamoDB table
+- A message sent to the Amazon SNS topic
+- A message sent to the Amazon SQS queue
+
+The go functions are in their respective sub-folders in **src**.
+
+## Using this code
+
+Copy the contents of this directory to your computer.
+If you want to change CloudFormation stack name from the
+current value **GoLambdaCdkStack**,
+change that value in **cdk.json**, **bin/go-lambda-cdk.ts** and **lib/go-lambda-cdk-stack.ts**
+to the value you prefer.
+
+You must run the following command to get the packages
+that this CDK app requires:
+
+`npm install`
+
+You'll know you have all of the packages you need
+if you can successfully execute the following command
+to create a CloudFormation stack from this CDK app:
+
+`cdk synth`
+
+This creates the template **GoLambdaCdkStack.template.json**
+(unless you've changed the stack name) in **cdk.out**.
+
+If you encounter any errors running CDK commands,
+see the
+[Troubleshooting common AWS CDK issues](https://docs.aws.amazon.com/cdk/latest/guide/troubleshooting.html#troubleshooting_toolkit)
+topic in the CDK developer guide.
+
+## Working with the CDK app
+
+If you aren't familiar with the CDK, here are some common commands:
+
+- `cdk deploy` deploy this stack to your default AWS account/region
+- `cdk diff`   compare deployed stack with current state
+- `cdk ls`     lists your CloudFormation stacks
+- `cdk synth`  create a CloudFormation template in 
+
+See [CDK command](https://docs.aws.amazon.com/cdk/latest/guide/cli.html)
+topic in the CDK developer guide for details.
+
+## Getting information about the new resources
+
+Once you deploy the application, it display the following information
+that you can use to work with the created resources:
+
+- The name of the resource
+- The name of the Lambda function that handles the events from the resource
+- The name of the Amazon CloudWatch log group to which
+  print statements from the AWS Lambda function are sent
+  
+You can use the CLI to get information about the resources created by
+the resulting CloudFormation template by running the following command,
+where *STACK-NAME* is the name of your CloudFormation stack:
+
+`aws cloudformation describe-stacks --stack-name STACK-NAME --query Stacks[0].Outputs --output text`
+
+## Testing the notifications
+
+This project contains the following Windows batch and Bash script files that you can use 
+to test the AWS Lambda functions by sending a JSON payload to the function specified on the command line:
+
+- **DynamoDBRecord.bat**, **DynamoDBRecord.sh**: these scripts send the data in **dynamodb-payload.json**.
+- **S3Record.bat**, **S3Record.sh**: these scripts send the data in **s3-payload.json**.
+- **SNSRecord.bat**, **SNSRecord.sh**: these scripts send the data in **sns-payload.json**.
+- **SQSRecord.sh**, **SQSRecord.bat**: these scripts send the data in **sqs-payload.json**.
