How do I change the demo content?

Where do I go to change the demo image and text? I don’t see it. Could someone please lend a hand?
Thanks

Hi there

Hope you are having a good day and thank you for your question
Well, some level of experience is necessary to work with WordPress, all you need is to change the content of the pages, posts, menus, you may wish to change the layout of the website and appearance, this can be done from appearance> customize
If you have a specific question let me know but overall all you need is small experience, also please take a look at our documentation

Thanks!
