I am still new to Ghost. I came from Wordpress. I really need to be able to edit the theme files to insert images into the header, or add privacy policies, etc to the footer and I seem to be running into an issue on how to do this. In WordPress, there was a theme editor that granted access to all of that, or widgets that let you insert text into the footer. I’m not really sure how to do this in Ghost. Do I need a program or something? Sorry for being a noob.
