+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:
-- Unlink the service
-- Change MYSQL_DATABASE_SCHEME to the desired setting
-- Relink the service
 
-## Configuration
+```shell
+dokku mysql:link other_service playground
+```
 
-It is possible to add custom configuration settings.
+It is possible to change the protocol for database_url by setting the environment variable database_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.
-`/etc/mysql/conf.d` is mapped to the output of `dokku mysql:info SERVICE --config-dir`
 
-Any files placed in this folder will be loaded. If a file is changed you will need
+```shell
-to reload your database for the changes to take effect.
+dokku config:set playground DATABASE_DATABASE_SCHEME=mysql2
+dokku mysql:link lolipop playground
+```
 
-For more information on configuration options see https://dev.mysql.com/doc/refman/5.7/en/option-files.html
+This will cause database_url to be set as:
 
-> 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.
+```
+mysql2://lolipop:SOME_PASSWORD@dokku-mysql-lolipop:3306/lolipop
+```
+
+### unlink the mysql service from the app
+
+```shell
+# usage
+dokku mysql:unlink <service> <app>
+```
+
+You can unlink a mysql service:
+
+> NOTE: this will restart your app and unset related environment variables
+
+```shell
+dokku mysql:unlink lolipop playground
+```
+
+### Service Lifecycle
+
+The lifecycle of each service can be managed through the following commands:
+
+### 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 ${PLUGIN_DATASTORE_PORTS[@]}
+```
+
+### 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
+```

+
+```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
+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.
-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:
 
+### sets up authentication for backups on the mysql service
+
+```shell
+# usage
+dokku mysql:backup-auth <service> <aws-access-key-id> <aws-secret-access-key> <aws-default-region> <aws-signature-version> <endpoint-url>
 ```
-# setup s3 backup authentication
+
+Setup s3 backup authentication:
+
+```shell
 dokku mysql:backup-auth lolipop AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY
-
-# remove s3 authentication
-dokku mysql:backup-deauth lolipop
-
-# backup the `lolipop` service to the `BUCKET_NAME` bucket on AWS
-dokku mysql:backup lolipop BUCKET_NAME
-
-# schedule a backup
-# CRON_SCHEDULE is a crontab expression, eg. "0 3 * * *" for each day at 3am
-dokku mysql:backup-schedule lolipop CRON_SCHEDULE BUCKET_NAME
-
-# 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:
- 
+
-```
+```shell
-# setup s3 backup authentication with different region
 dokku mysql: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
 dokku mysql:backup-auth lolipop AWS_ACCESS_KEY_ID AWS_SECRET_ACCESS_KEY AWS_REGION AWS_SIGNATURE_VERSION ENDPOINT_URL
- 
+```
-# more specific example for minio auth
+
+More specific example for minio auth:
+
+```shell
 dokku mysql:backup-auth lolipop MINIO_ACCESS_KEY_ID MINIO_SECRET_ACCESS_KEY us-east-1 s3v4 https://YOURMINIOSERVICE
 ```
 
-## Disabling `docker pull` calls
+### removes backup authentication for the mysql service
+
+```shell
+# usage
+dokku mysql:backup-deauth <service>
+```
+
+Remove s3 authentication:

+
+```shell
+# usage
+dokku mysql:backup <service> <bucket-name> [--use-iam]
+```
+
+Backup the 'lolipop' service to the 'my-s3-bucket' bucket on aws:
+
+```shell
+dokku mysql:backup lolipop my-s3-bucket --use-iam
+```
+
+### sets encryption for all future backups of mysql service
+
+```shell
+# usage
+dokku mysql:backup-set-encryption <service> <passphrase>
+```
+
+Set a gpg passphrase for backups:
+
+```shell
+dokku mysql:backup-set-encryption lolipop
+```
+
+### unsets encryption for future backups of the mysql service
+
+```shell
+# usage
+dokku mysql:backup-unset-encryption <service>
+```
+
+Unset a gpg encryption key for backups:
+
+```shell
+dokku mysql:backup-unset-encryption lolipop
+```
+
+### schedules a backup of the mysql service
+
+```shell
+# usage
+dokku mysql:backup-schedule <service> <schedule> <bucket-name> [--use-iam]
+```
+
+Schedule a backup:
+
+> 'schedule' is a crontab expression, eg. "0 3 * * *" for each day at 3am
+
+```shell
+dokku mysql:backup-schedule lolipop "0 3 * * *" my-s3-bucket
+```
+
+Schedule a backup and authenticate via iam:
+
+```shell
+dokku mysql:backup-schedule lolipop "0 3 * * *" my-s3-bucket --use-iam
+```
+
+### cat the contents of the configured backup cronfile for the service
+
+```shell
+# usage
+dokku mysql:backup-schedule-cat <service>
+```
+
+Cat the contents of the configured backup cronfile for the service:
+
+```shell
+dokku mysql:backup-schedule-cat lolipop
+```
+
+### unschedules the backup of the mysql service
+
+```shell
+# usage
+dokku mysql:backup-unschedule <service>
+```
+
+Remove the scheduled backup from cron:
+
+```shell
+dokku mysql:backup-unschedule lolipop
+```
+
+### Disabling `docker pull` calls
 
 If you wish to disable the `docker pull` calls that the plugin triggers, you may set the `MYSQL_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.
