sudo groupadd docker
~~~

Service management
The service itself does not require particular management as all features are embedded in the client interface running from the docker container 'sl-app', including user management. Parameters can only be amended through the config file under the root user:
sudo vim ~/simplelogin.env
Sample configs can be found here
Once the change is made, restart the app container:
~~~bash
docker restart sl-app
~~~
Force premium subscription for users
#^Top Users will be defaulted to the 'Free' plan and asked to subscribe to the premium plan. In order to force users onto the Premium plan, please update the database:
~~~bash
docker exec -it sl-db psql -U (dbusername) simplelogin
~~~
And then run:
~~~bash
UPDATE users SET lifetime = 'TRUE' WHERE EMAIL = '(emailaddress)';
~~~
And \q to exit the db.
