 # Wait for ECR Scan and get Sarif GitHub Action
 
-### Easily upload coverage reports to Codecov from GitHub Actions
+This action is used for integrating AWS ECR Image Scanning with GitHub security.
+GitHub security integrates with the Sarif standard, allowing Sarif json files to be uploaded and displayed in the Security tab's code scanning results.
+The AWS API's describe-image-scan-findings response is not compatible with the Sarif standard.
+This GitHub action waits for AWS image scanning process to complete on a provided tag, takes the AWS API response from describe-image-scan-findings, and converts it to the standard Sarif format.
