Switch Suitecrm in https - ssl

I just installed suitecrm and I don’t understand how enable ssl in the front.
I use alwaysdata as hosting service and I’m sure ssl certificate is activate (as 10 another website I manage to this host).
I’m asking if there is an option to enable https in the admin section of suitecrm or if I have to write some code in php or activate some fonction.
Thanks a lot for your help.

Just make sure your host_name and site_url settings are ok in config.php

By “ok” I just mean, if you see an http there, change it to https
