 ## Usage
 Deploy the container in an environment where it inherits an IAM role (i.e. an ECS task role), or provide the environment variables necessary to get `aws-cli` to pick up the credentials. To specify what files to expose, set the following environment variables:
 - `BUCKET` should be the bucket you wish to retrieve the files from
-- `FILES` is a `|`-delimited list of files within the bucket you wish to be exposed. Their full key will be used
+- `FILES` is a `|`-delimited list of files within the bucket you wish to be exposed. Their full key will be used unless you use the `BASENAME` flag.
+- `BASENAME` should be set to 1 if you want the files to be renamed to be only the basename (so `/opt/basename` vs `/opt/full/key/path/basename`).
 
 The files will be exposed in a volume in `/opt`, which you should then mount in to any other containers you wish to acccess the files.
