 This blueprint expects files uploaded to an S3 source bucket which trigger S3 event notifications and publish file metadata to SQS. On a regular 2 minute CloudWatch event rule, a Lambda function is invoked which checks the SQS queue for the `ApproximateNumberOfMessages` attribute and lauches Fargate tasks based on queue depth using the ECS `run_task()` API. The tasks are designed to continue processing and draining the SQS queue before scaling down to 0 tasks automatically, eliminating the need to keep a fixed pool of ECS tasks running.
 
 * Deploy the [core-infra](../core-infra/README.md). Note if you have already deployed the infra then you can reuse it as well.
+* Create a [Github token](https://docs.github.com/en/authentication/keeping-your-account-and-data-secure/creating-a-personal-access-token) to access the forked repository.
+* Store the secret in AWS Secrets Manager in the region where you want to deploy the blueprints.
+  ```shell
+  aws secretsmanager create-secret --name ecs-github-token --secret-string <your-github-access-token>
+  ```
 * **NOTE:** Codestar notification rules require a **one-time** creation of a service-linked role. Please verify one exists or create the codestar-notification service-linked role.
   * `aws iam get-role --role-name AWSServiceRoleForCodeStarNotifications`
