[glance] Doc about swift as backend

Hi everyone, Are there any specific documentation about how to configure Swift as backend of Glance service? I've found this: https://docs.openstack.org/glance/latest/configuration/configuring.html but I'm not sure what are the options I need. Firstly, I follow the installation guides of glance: https://docs.openstack.org/glance/latest/install/install-ubuntu.html and I have now file as store but I'rather change it. Thanks!
