+AWS Integration
+---------------
+
+**autoapi** synchronizes with the S3 bucket specified in the `AUTOAPI_BUCKET` environment variable. On starting the API server, **autoapi** creates a subscription to the target bucket using Amazon SNS. When files are added to or deleted from the bucket, the corresponding endpoints will automatically be updated on the API.
