I'm attaching the screenshot, but your best option is still to install the shaper somewhere for reference.
Installing the shaper takes only as long as a typical WP install; there is nothing different in the process. All you have to do is upload the shaper then go through the install the same way you would if it was normal WP. Uploading the files takes more time than the 1-5 minutes of actually going through the install.
As for the issue with formatting, the "RAW HTML" option on the "Content" tab of the theme settings will re-enable the auto-formatting that WP usually applies; this option had to be added for demo content that uses custom HTML because WP was breaking things.
I'm not sure what you mean about it being difficult to update. The majority of the demo content is controlled with widgets; using
Widget Context to show or hide each widget on specific sections of the site if they aren't intended to be viewed globally across the site. There's even a URL toggle that will label each section of the site on the front end, so you can see where the widgets are located:
