All of Azuriom's market extensions can be downloaded directly from the admin panel of a site with Azuriom. To install this extension, simply go to the tab 'Theme' of the admin dashboard.
As this extension is paid, if you have not yet done so, it's necessary to enter your site key (available on your profile) in the general parameters of your site, in the field 'azuriom.com site key'.
Once done, it may be necessary to reload the themes/plugins.
