+# Rekognition Lambda S3 Trigger
+
+
+## How it works
+
+This project creates the following in your AWS account:
+
+- S3 bucket
+- DynamoDB table
+- Lambda function that performs image classification via AWS Rekognition when new images are uploaded to the S3 bucket
+- Roles and policies allowing appropriate access to these resources
+- Rekognition labels are written to the DynamoDb table.
+
+## Deploy
+Run `cdk deploy`. This will deploy / redeploy your Stack to your AWS Account.
+
+## Manage GO dependencies
+Run `go mod tidy`
+
+## Synthesize Cloudformation Template
+To see the Cloudformation template generated by the CDK, run `cdk synth`.
