 Creates a Docker container that is restored and backed up to a directory on s3.
 You could use this to run short lived processes that work with and persist data to and from S3.
 
-Usage:
+## Usage
 
-    docker run -it --rm \
-      -e AWS_ACCESS_KEY_ID=... -e AWS_SECRET_ACCESS_KEY=... -e BACKUP_INTERVAL=... \
-      elementar/s3-volume s3://<BUCKET>/<PATH>
+For the simplest usage, you can just start the data container:
 
-This pulls down the contents of a directory on S3. If the container is stopped or sent a `USR1` signal,
-it will backup the modified local contents to S3.
+```bash
+docker run -d --name my-data-container \
+           elementar/s3-volume s3://mybucket/someprefix
+```
 
-If you supply a `BACKUP_INTERVAL` environment variable, a backup will be issued each interval. The value can
-be specified in seconds, minutes, hours or days (adding `s`, `m`, `h` or `d` as suffix).
+This will download the data from the S3 location you specify into the
+container's `/data` directory. When the container shuts down, the data will be
+synced back to S3.
+
+To use the data from another container, you can use the `--volumes-from` option:
+
+```bash
+docker run -it --rm --volumes-from=my-data-container busybox ls -l /data
+```
+
+### Configuring a sync interval
+
+When the `BACKUP_INTERVAL` environment variable is set, a watcher process will
+sync the `/data` directory to S3 on the interval you specify. The interval can
+be specified in seconds, minutes, hours or days (adding `s`, `m`, `h` or `d` as
+the suffix):
+
+```bash
+docker run -d --name my-data-container -e BACKUP_INTERVAL=2m \
+           elementar/s3-volume s3://mybucket/someprefix
+```
+
+### Configuring credentials
+
+If you are running on EC2, IAM role credentials should just work. Otherwise,
+you can supply credential information using environment variables:
+
+```bash
+docker run -d --name my-data-container \
+           -e AWS_ACCESS_KEY_ID=... -e AWS_SECRET_ACCESS_KEY=... \
+           elementar/s3-volume s3://mybucket/someprefix
+```
+
+Any environment variable available to the `aws-cli` command can be used. see
+http://docs.aws.amazon.com/cli/latest/userguide/cli-environment.html for more
+information.
+
+### Forcing a sync
+
+A final sync will always be performed on container shutdown. A sync can be
+forced by sending the container the `USR1` signal:
+
+```bash
+docker kill --signal=USR1 my-data-container
+```
+
+### Forcing a restoration
+
+The first time the container is ran, it will fetch the contents of the S3
+location to initialize the `/data` directory. If you want to force an initial
+sync again, you can run the container again with the `--force-restore` option:
+
+```bash
+docker run -d --name my-data-container \
+           elementar/s3-volume --force-restore s3://mybucket/someprefix
+```
+
+### Using Compose and named volumes
+
+Most of the time, you will use this image to sync data for another container.
+You can use `docker-compose` for that:
+
+```yaml
+# docker-compose.yaml
+version: "2"
+
+volumes:
+  s3vol:
+    driver: local
+
+services:
+  s3vol:
+    image: elementar/s3-volume
+    command: s3://mybucket/someprefix
+    volumes:
+      - s3vol:/data
+  db:
+    image: postgres
+    volumes:
+      - s3vol:/var/lib/postgresql/data
+```
