There shouldn't be a need for a guide it is very straightforward, please let me know if you have questions after trying it, thanks!

You are right, it's pretty straightforward. But you have to go through it in a trial-and-error kind of way. And a simple documentation would save time and give confidence in the workings of the tool. Maybe if there's time, users can write something once having gone through a site build process thoroughly.
