To publish the Docker documentation you need to set your access_key and secret_key in the docs/awsconfig file 
(with the keys in a [profile $AWS_S3_BUCKET] section - so you can have more than one set of keys in your file)
and set the AWS_S3_BUCKET env var to the name of your bucket.

If you're publishing the current release's documentation, also set `BUILD_ROOT=yes`

make AWS_S3_BUCKET=docs-stage.docker.com docs-release

will then push the documentation site to your s3 bucket.
