+The host exposed here only works internally in docker containers. If you want your container to be reachable from outside, you should use the 'expose' subcommand. Another service can be linked to your app:
+
+```shell
+dokku redis:link other_service playground
+```
+
+It is possible to change the protocol for `REDIS_URL` by setting the environment variable `REDIS_DATABASE_SCHEME` on the app. Doing so will after linking will cause the plugin to think the service is not linked, and we advise you to unlink before proceeding. 
+
+```shell
 dokku config:set playground REDIS_DATABASE_SCHEME=redis2
 dokku redis:link lolipop playground

+```
 
-CAUTION: Changing REDIS_DATABASE_SCHEME after linking will cause dokku to
-believe the redis is not linked when attempting to use `dokku redis:unlink`
-or `dokku redis:promote`.
-You should be able to fix this by
+### unlink the redis service from the app
 
-- Changing REDIS_URL manually to the new value.
+```shell
+# usage
+dokku redis:unlink <service> <app>
+```
 
-OR
+You can unlink a redis service:
 
-- Set REDIS_DATABASE_SCHEME back to its original setting
-- Unlink the service
-- Change REDIS_DATABASE_SCHEME to the desired setting
-- Relink the service
+> NOTE: this will restart your app and unset related environment variables
 
-## Backups
+```shell
+dokku redis:unlink lolipop playground
+```
+
+### Service Lifecycle
+
+The lifecycle of each service can be managed through the following commands:
+
+### connect to the service via the redis connection tool
+
+```shell
+# usage
+dokku redis:connect <service>
+```
+
+Connect to the service via the redis connection tool:
+
+```shell
+dokku redis:connect lolipop
+```
+
+### enter or run a command in a running redis service container
+
+```shell
+# usage
+dokku redis:enter <service>
+```
+
+A bash prompt can be opened against a running service. Filesystem changes will not be saved to disk. 
+
+```shell
+dokku redis:enter lolipop
+```
+
+You may also run a command directly against the service. Filesystem changes will not be saved to disk. 
+
+```shell
+dokku redis:enter lolipop touch /tmp/test
+```
+
+### expose a redis service on custom port if provided (random port otherwise)
+
+```shell
+# usage
+dokku redis:expose <service> <ports...>
+```
+
+Expose the service on the service's normal ports, allowing access to it from the public interface (`0.0.0.0`):
+
+```shell
+dokku redis:expose lolipop 6379
+```
+
+### unexpose a previously exposed redis service
+
+```shell
+# usage
+dokku redis:unexpose <service>
+```
+
+Unexpose the service, removing access to it from the public interface (`0.0.0.0`):
+
+```shell
+dokku redis:unexpose lolipop
+```
+
+### promote service <service> as REDIS_URL in <app>
+
+```shell
+# usage
+dokku redis:promote <service> <app>
+```
+
+If you have a redis service linked to an app and try to link another redis service another link environment variable will be generated automatically:
+
+```
+DOKKU_REDIS_BLUE_URL=redis://other_service:ANOTHER_PASSWORD@dokku-redis-other-service:6379/other_service
+```
+
+You can promote the new service to be the primary one:
+
+> NOTE: this will restart your app
+
+```shell
+dokku redis:promote other_service playground
+```
+
+This will replace `REDIS_URL` with the url from other_service and generate another environment variable to hold the previous value if necessary. You could end up with the following for example:
+
+```
+REDIS_URL=redis://other_service:ANOTHER_PASSWORD@dokku-redis-other-service:6379/other_service
+DOKKU_REDIS_BLUE_URL=redis://other_service:ANOTHER_PASSWORD@dokku-redis-other-service:6379/other_service
+DOKKU_REDIS_SILVER_URL=redis://lolipop:SOME_PASSWORD@dokku-redis-lolipop:6379/lolipop
+```
+
+### start a previously stopped redis service
+
+```shell
+# usage
+dokku redis:start <service>
+```
+
+Start the service:
+
+```shell
+dokku redis:start lolipop
+```
+
+### stop a running redis service
+
+```shell
+# usage
+dokku redis:stop <service>
+```
+
+Stop the service and the running container:
+
+```shell
+dokku redis:stop lolipop
+```
+
+### graceful shutdown and restart of the redis service container
+
+```shell
+# usage
+dokku redis:restart <service>
+```
+
+Restart the service:
+
+```shell
+dokku redis:restart lolipop
+```
+
+### upgrade service <service> to the specified versions
+
+```shell
+# usage
+dokku redis:upgrade <service> [--upgrade-flags...]
+```
+
+flags:
+
+- `-C|--custom-env "USER=alpha;HOST=beta"`: semi-colon delimited environment variables to start the service with
+- `-i|--image IMAGE`: the image name to start the service with
+- `-I|--image-version IMAGE_VERSION`: the image version to start the service with
+- `-R|--restart-apps "true"`: whether to force an app restart
+
+You can upgrade an existing service to a new image or image-version:
+
+```shell
+dokku redis:upgrade lolipop
+```
+
+### Service Automation
+
+Service scripting can be executed using the following commands:
+
+### list all redis service links for a given app
+
+```shell
+# usage
+dokku redis:app-links <app>
+```
+
+List all redis services that are linked to the 'playground' app. 
+
+```shell
+dokku redis:app-links playground
+```
+
+### create container <new-name> then copy data from <name> into <new-name>
+
+```shell
+# usage
+dokku redis:clone <service> <new-service> [--clone-flags...]
+```
+
+flags:
+
+- `-C|--custom-env "USER=alpha;HOST=beta"`: semi-colon delimited environment variables to start the service with
+- `-i|--image IMAGE`: the image name to start the service with
+- `-I|--image-version IMAGE_VERSION`: the image version to start the service with
+- `-p|--password PASSWORD`: override the user-level service password
+- `-r|--root-password PASSWORD`: override the root-level service password
+
+You can clone an existing service to a new one:
+
+```shell
+dokku redis:clone lolipop lolipop-2
+```
+
+### check if the redis service exists
+
+```shell
+# usage
+dokku redis:exists <service>
+```
+
+Here we check if the lolipop redis service exists. 
+
+```shell
+dokku redis:exists lolipop
+```
+
+### check if the redis service is linked to an app
+
+```shell
+# usage
+dokku redis:linked <service> <app>
+```
+
+Here we check if the lolipop redis service is linked to the 'playground' app. 
+
+```shell
+dokku redis:linked lolipop playground
+```
+
+### list all apps linked to the redis service
+
+```shell
+# usage
+dokku redis:links <service>
+```
+
+List all apps linked to the 'lolipop' redis service. 
+
+```shell
+dokku redis:links lolipop
+```
+
+### Data Management
+
+The underlying service data can be imported and exported with the following commands:
+
+### import a dump into the redis service database
+
+```shell
+# usage
+dokku redis:import <service>
+```
+
+Import a datastore dump:
+
+```shell
+dokku redis:import lolipop < database.dump
+```
+
+### export a dump of the redis service database
+
+```shell
+# usage
+dokku redis:export <service>
+```
+
+By default, datastore output is exported to stdout:
+
+```shell
+dokku redis:export lolipop
+```
+
+You can redirect this output to a file:
+
+```shell
+dokku redis:export lolipop > lolipop.dump
+```
+
+### Backups
 
 Datastore backups are supported via AWS S3 and S3 compatible services like [minio](https://github.com/minio/minio).
 
-You may skip the `backup-auth` step if your dokku install is running within EC2
-and has access to the bucket via an IAM profile. In that case, use the `--use-iam`
-option with the `backup` command.

 Backups can be performed using the backup commands:

 ```

-# remove s3 authentication

-
-# backup the `lolipop` service to the `BUCKET_NAME` bucket on AWS
-dokku redis:backup lolipop BUCKET_NAME
-
-# schedule a backup
-# CRON_SCHEDULE is a crontab expression, eg. "0 3 * * *" for each day at 3am
-dokku redis:backup-schedule lolipop CRON_SCHEDULE BUCKET_NAME
-
-# cat the contents of the configured backup cronfile for the service
-dokku redis:backup-schedule-cat lolipop
-
-# remove the scheduled backup from cron
-dokku redis:backup-unschedule lolipop
 ```
 
-Backup auth can also be set up for different regions, signature versions and endpoints (e.g. for minio):
- 
-```
-# setup s3 backup authentication with different region
+Setup s3 backup authentication with different region:
+
+```shell
 dokku redis:backup-auth lolipop AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY AWS_REGION
- 
-# setup s3 backup authentication with different signature version and endpoint
+```
+
+Setup s3 backup authentication with different signature version and endpoint:
+
+```shell

+
+```shell

+
+### Disabling `docker pull` calls
 
 If you wish to disable the `docker pull` calls that the plugin triggers, you may set the `REDIS_DISABLE_PULL` environment variable to `true`. Once disabled, you will need to pull the service image you wish to deploy as shown in the `stderr` output.
 
-Please ensure the proper images are in place when `docker pull` is disabled.
