+## Removing files from the docs.docker.com site
+
+Sometimes it becomes necessary to remove files from the historical published documentation.
+The most reliable way to do this is to do it directly using `aws s3` commands running in a
+docs container:
+
+Start the docs container like `make docs-shell`, but bind mount in your `awsconfig`:
+
+```
+docker run --rm -it -v $(CURDIR)/docs/awsconfig:/docs/awsconfig docker-docs:master bash
+```
+
+and then the following example shows deleting 2 documents from s3, and then requesting the
+CloudFlare cache to invalidate them:
+
+
+```
+export BUCKET BUCKET=docs.docker.com
+export AWS_CONFIG_FILE=$(pwd)/awsconfig
+aws s3 --profile $BUCKET ls s3://$BUCKET
+aws s3 --profile $BUCKET rm s3://$BUCKET/v1.0/reference/api/docker_io_oauth_api/index.html
+aws s3 --profile $BUCKET rm s3://$BUCKET/v1.1/reference/api/docker_io_oauth_api/index.html
+
+aws configure set preview.cloudfront true
+export DISTRIBUTION_ID=YUTIYUTIUTIUYTIUT
