I set up my new site and imported the demo data. I don’t want to start from scratch. Can I simply replace images/buttons/text that came with the demo data for the slider on the home page?
You can easily edit the demo data content. If you want to change the slider, then go to Codeless slider menu and change the images, buttons and text. For more info please read the theme doc https://codeless.co/documentation or watch the video tutorials https://support.codeless.co/?page_id=45
