Hi there,
The term “Dashboard” refers to the admin area of your WordPress installation.
So, if you’ve installed WordPress, you can go to yourwebsite.com/wp-admin – this is your Dashboard.
From there, you can follow the rest of the instructions to upload GP Premium: http://generatepress.com/knowledgebase/install-activate-addons/
Let me know if you need more info 🙂
