Running and troubleshooting for CertBot can be found [here ](https://certbot.eff.org/docs/install.html )

#### 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:
```ad-path
sudo vim ~/simplelogin.env
```
Sample configs can be found [here ](https://github.com/simple-login/app/blob/master/example.env )
Once the change is made, restart the app container:
```ad-command
~~~bash
docker restart sl-app
~~~
```
 
##### Force premium subscription for users
[[#^Top|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:
```ad-command
~~~bash
docker exec -it sl-db psql -U (dbusername) simplelogin
~~~
```
And then run:
```ad-command
~~~bash
UPDATE users SET lifetime = 'TRUE' WHERE EMAIL = '(emailaddress)';
