+
+```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

-believe the redis is not linked when attempting to use `dokku redis:unlink`

+### unlink the redis service from the app

+```shell

-- Relink the service

+> NOTE: this will restart your app and unset related environment variables
+
+```shell

+
+### 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://: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://:ANOTHER_PASSWORD@dokku-redis-other-service:6379/other_service
+DOKKU_REDIS_BLUE_URL=redis://:ANOTHER_PASSWORD@dokku-redis-other-service:6379/other_service
+DOKKU_REDIS_SILVER_URL=redis://:SOME_PASSWORD@dokku-redis-lolipop:6379/lolipop
+```
+
+### start a previously stopped redis 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:

+
+### graceful shutdown and restart of the redis service container

+```
+
+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
+```
+
