-dokku mysql:import lolipop < database.sql
-
-# you can clone an existing database to a new one
-dokku mysql:clone lolipop new_database
-

 ```
 
-## Changing database adapter
+By default, logs will not be tailed, but you can do this with the --tail flag:
 
-It's possible to change the protocol for DATABASE_URL by setting
-the environment variable MYSQL_DATABASE_SCHEME on the app:
+```shell

+```
+
+### link the mysql service to the app
+
+```shell
+# usage
+dokku mysql:link <service> <app> [--link-flags...]
+```
+

+- `-a|--alias "BLUE_DATABASE"`: an alternative alias to use for linking to an app via environment variable
+- `-q|--querystring "pool=5"`: ampersand delimited querystring arguments to append to the service link
+
+A mysql service can be linked to a container. This will use native docker links via the docker-options plugin. Here we link it to our 'playground' app. 
+
+> NOTE: this will restart your app
+
+```shell
+dokku mysql:link lolipop playground
+```
+
+The following environment variables will be set automatically by docker (not on the app itself, so they won’t be listed when calling dokku config):
 
 ```
+DOKKU_DATABASE_LOLIPOP_NAME=/lolipop/DATABASE
+DOKKU_DATABASE_LOLIPOP_PORT=tcp://172.17.0.1:3306
+DOKKU_DATABASE_LOLIPOP_PORT_3306_TCP=tcp://172.17.0.1:3306
+DOKKU_DATABASE_LOLIPOP_PORT_3306_TCP_PROTO=tcp
+DOKKU_DATABASE_LOLIPOP_PORT_3306_TCP_PORT=3306
+DOKKU_DATABASE_LOLIPOP_PORT_3306_TCP_ADDR=172.17.0.1
+```
+
+The following will be set on the linked application by default:
+
+```
+DATABASE_URL=mysql://lolipop:SOME_PASSWORD@dokku-mysql-lolipop:3306/lolipop
+```
+
+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 mysql:link other_service playground
+```
+
+It is possible to change the protocol for `DATABASE_URL` by setting the environment variable `MYSQL_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 MYSQL_DATABASE_SCHEME=mysql2
 dokku mysql:link lolipop playground
 ```
 
-Will cause DATABASE_URL to be set as
-mysql2://mysql:SOME_PASSWORD@dokku-mysql-lolipop:3306/lolipop
+This will cause `DATABASE_URL` to be set as:
 
-CAUTION: Changing MYSQL_DATABASE_SCHEME after linking will cause dokku to
-believe the service is not linked when attempting to use `dokku mysql:unlink`
-or `dokku mysql:promote`.
-You should be able to fix this by
+```
+mysql2://lolipop:SOME_PASSWORD@dokku-mysql-lolipop:3306/lolipop
+```
 
-- Changing DATABASE_URL manually to the new value.
+### unlink the mysql service from the app
 
-OR
+```shell
+# usage
+dokku mysql:unlink <service> <app>
+```
 
-- Set MYSQL_DATABASE_SCHEME back to its original setting
-- Unlink the service
-- Change MYSQL_DATABASE_SCHEME to the desired setting
-- Relink the service
+You can unlink a mysql service:
 
-## Configuration
+> NOTE: this will restart your app and unset related environment variables
 
-It is possible to add custom configuration settings.
-`/etc/mysql/conf.d` is mapped to the output of `dokku mysql:info SERVICE --config-dir`
+```shell
+dokku mysql:unlink lolipop playground
+```
 
-Any files placed in this folder will be loaded. If a file is changed you will need
-to reload your database for the changes to take effect.
+### Service Lifecycle
 
-For more information on configuration options see https://dev.mysql.com/doc/refman/5.7/en/option-files.html
+The lifecycle of each service can be managed through the following commands:
 
-> Note: This plugin mounts a host directory into the container under `/etc/mysql/conf.d`. Custom images that have files in this directory will have those files overwritten by the mount.
+### connect to the service via the mysql connection tool
+
+```shell
+# usage
+dokku mysql:connect <service>
+```
+
+Connect to the service via the mysql connection tool:
+
+```shell
+dokku mysql:connect lolipop
+```
+
+### enter or run a command in a running mysql service container
+
+```shell
+# usage
+dokku mysql:enter <service>
+```
+
+A bash prompt can be opened against a running service. Filesystem changes will not be saved to disk. 
+
+```shell
+dokku mysql:enter lolipop
+```
+
+You may also run a command directly against the service. Filesystem changes will not be saved to disk. 
+
+```shell
+dokku mysql:enter lolipop touch /tmp/test
+```
+
+### expose a mysql service on custom port if provided (random port otherwise)
+
+```shell
+# usage
+dokku mysql: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 mysql:expose lolipop 3306
+```
+
+### unexpose a previously exposed mysql service
+
+```shell
+# usage
+dokku mysql:unexpose <service>
+```
+
+Unexpose the service, removing access to it from the public interface (`0.0.0.0`):
+
+```shell
+dokku mysql:unexpose lolipop
+```
+
+### promote service <service> as DATABASE_URL in <app>
+
+```shell
+# usage
+dokku mysql:promote <service> <app>
+```
+
+If you have a mysql service linked to an app and try to link another mysql service another link environment variable will be generated automatically:
+
+```
+DOKKU_DATABASE_BLUE_URL=mysql://other_service:ANOTHER_PASSWORD@dokku-mysql-other-service:3306/other_service
+```
+
+You can promote the new service to be the primary one:
+
+> NOTE: this will restart your app
+
+```shell
+dokku mysql:promote other_service playground
+```
+
+This will replace `DATABASE_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:
+
+```
+DATABASE_URL=mysql://other_service:ANOTHER_PASSWORD@dokku-mysql-other-service:3306/other_service
+DOKKU_DATABASE_BLUE_URL=mysql://other_service:ANOTHER_PASSWORD@dokku-mysql-other-service:3306/other_service
+DOKKU_DATABASE_SILVER_URL=mysql://lolipop:SOME_PASSWORD@dokku-mysql-lolipop:3306/lolipop
+```
+
+### start a previously stopped mysql service
+
+```shell
+# usage
+dokku mysql:start <service>
+```
+
+Start the service:
+
+```shell
+dokku mysql:start lolipop
+```
+
+### stop a running mysql service
+
+```shell
+# usage
+dokku mysql:stop <service>
+```
+
+Stop the service and the running container:
+
+```shell
+dokku mysql:stop lolipop
+```
+
+### graceful shutdown and restart of the mysql service container
+
+```shell
+# usage
+dokku mysql:restart <service>
+```
+
+Restart the service:
+
+```shell
+dokku mysql:restart lolipop
+```
+
+### upgrade service <service> to the specified versions
+
+```shell
+# usage
+dokku mysql: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 mysql:upgrade lolipop
+```
+
+### Service Automation
+
+Service scripting can be executed using the following commands:
+
+### list all mysql service links for a given app
+
+```shell
+# usage
+dokku mysql:app-links <app>
+```
+
+List all mysql services that are linked to the 'playground' app. 
+
+```shell
+dokku mysql:app-links playground
+```
+
+### create container <new-name> then copy data from <name> into <new-name>
+
+```shell
+# usage
+dokku mysql: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 mysql:clone lolipop lolipop-2
+```
+
+### check if the mysql service exists
+
+```shell
+# usage
+dokku mysql:exists <service>
+```
+
+Here we check if the lolipop mysql service exists. 
+
+```shell
+dokku mysql:exists lolipop
+```
+
+### check if the mysql service is linked to an app
+
+```shell
+# usage
+dokku mysql:linked <service> <app>
+```
+
+Here we check if the lolipop mysql service is linked to the 'playground' app. 
+
+```shell
+dokku mysql:linked lolipop playground
+```
+
+### list all apps linked to the mysql service
+
+```shell
+# usage
+dokku mysql:links <service>
+```
+
+List all apps linked to the 'lolipop' mysql service. 
+
+```shell
+dokku mysql:links lolipop
+```
+
+### Data Management
+
+The underlying service data can be imported and exported with the following commands:
+
+### import a dump into the mysql service database
+
+```shell
+# usage
+dokku mysql:import <service>
+```
+
+Import a datastore dump:
+
+```shell
+dokku mysql:import lolipop < database.dump
+```
+
+### export a dump of the mysql service database
+
+```shell
+# usage
+dokku mysql:export <service>
+```
+
+By default, datastore output is exported to stdout:
+
+```shell
+dokku mysql:export lolipop
+```
+
+You can redirect this output to a file:
+
+```shell
+dokku mysql: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.

-
-# cat the contents of the configured backup cronfile for the service
-dokku mysql:backup-schedule-cat lolipop
-
-# remove the scheduled backup from cron
-dokku mysql: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
