Convert Static Website (and format) Into Ghost

I’m trying to avoid making a custom theme.

Is there a reason you’re trying to avoid making a custom theme? :slight_smile:

I guess my real question is how to keep the same structure I have and styling and turn it into a theme?

This piece of documentation might help you to work out how to convert your static site structure into a Ghost theme:
