+# Copying a file from S3 to S3 via Eventbridge Pipes & Step Function
+
+This pattern shows how to use S3 Event Notifications, queue them on SQS, and then use EventBridge Pipes to launch a 
+StepFunctions state machine and copy the file from the source S3 bucket to a destination.  Modifying the state machine 
+would allow manipulation of the file.
+
+Important: this application uses various AWS services and there are costs associated with these services after the Free Tier usage - please see the [AWS Pricing page](https://aws.amazon.com/pricing/) for details. You are responsible for any AWS costs incurred. No warranty is implied in this example.
+
+## Requirements
+
+* [Create an AWS account](https://portal.aws.amazon.com/gp/aws/developer/registration/index.html) if you do not already have one and log in. The IAM user that you use must have sufficient permissions to make necessary AWS service calls and manage AWS resources.
+* [AWS CLI](https://docs.aws.amazon.com/cli/latest/userguide/install-cliv2.html) installed and configured
+* [Git Installed](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git)
+* [AWS Serverless Application Model](https://docs.aws.amazon.com/serverless-application-model/latest/developerguide/serverless-sam-cli-install.html) (AWS SAM) installed
+
+## Deployment Instructions
+
+1. Create a new directory, navigate to that directory in a terminal and clone the GitHub repository:
+    ``` 
+    git clone https://github.com/aws-samples/serverless-patterns
+    ```
+2. Change directory to the pattern directory:
+    ```
+    cd s3-sqs-eventbridge-pipe-sfn-s3
+    ```
+3. From the command line, use AWS SAM to deploy the AWS resources for the pattern as specified in the template.yml file:
+    ```
+    sam deploy --guided
+    ```
+4. During the prompts:
+    * Enter a stack name
+    * Enter the desired AWS Region
+    * Allow SAM CLI to create IAM roles with the required permissions.
+
+    Once you have run `sam deploy --guided` mode once and saved arguments to a configuration file (samconfig.toml),  you 
+   can use `sam deploy` in future to use these defaults.
+
+5. Note the outputs from the SAM deployment process. These contain the resource names and/or ARNs which are used for testing.
+
+## How it works
+
+When a file is created in the source S3 bucket, an 
+[S3 Event Notification](https://docs.aws.amazon.com/AmazonS3/latest/userguide/EventNotifications.html) fires with
+[this structure](https://docs.aws.amazon.com/AmazonS3/latest/userguide/notification-content-structure.html). 
+This is enqueued onto a standard Amazon SQS Queue.
+
+The EventBridge service polls the SQS Queue and invokes the EventBridge Pipe synchronously with an event that contains queue 
+messages. EventBridge reads messages in batches and invokes the pipe once for each batch. When the pipe successfully 
+processes a batch, EventBridge deletes its messages from the queue.
+The structure of the batch is [described here](https://docs.aws.amazon.com/eventbridge/latest/userguide/eb-pipes-sqs.html)
+
+The EventBridge Pipe then executes the 
+[AWS Step Functions Express Workflow](https://docs.aws.amazon.com/step-functions/latest/dg/concepts-standard-vs-express.html) 
+state machine 
+[described in s3-sqs-eventbridge-pipe-sfn-s3.asl.json](./workflow/s3-sqs-eventbridge-pipe-sfn-s3.asl.json). 
+This loops through each message in the batch dequeued from SQS using a Map state, loops through each record from the S3 
+Event Notification using another Map state, and then copies the file from the source S3 Bucket to the destination S3 
+Bucket. In a real world scenario the state machine would be modified to manipulate the file as desired.
+
+
+## Testing
+
+Provide steps to trigger the integration and show what should be observed if successful.
+
+1. Stream logs from StepFunctions LogGroup 
+
+```
+sam logs --cw-log-group <LogGroup Name> --tail
+```
+
+2. Put a file into the source bucket
+
+```
+aws s3api put-object --bucket <source-bucket-name> --key <source-bucket-filename> --body <local-filename>
+```
+
+3. Observe the logs for the new execution.
+
+## Cleanup
+
+1. Delete the stack
+
+ ```bash
+ sam delete
+ ```
