Hi - A client of mine has asked that I make some content updates and structural html changes to their existing Surreal CMS site. Essentially we are doing an entire site refresh. Is there an option to perform these structural changes offline (i.e. make a copy of their site) and then view these changes for sign-off with the client before pushing them live, without affecting the live site? I’m wondering what the best practices are for handling these types of updates? The documentation provides an overview on setting up your first site, but I didn’t see the recommended process for modifying an existing site including changes to css, html, and js files. Any information and/or recommendations you can provide would be very much appreciated.
