As for RW… no doc is really needed because it’s only role is to output the html/php page files. See page 29 of the RW PDF instruction doc. Once you have your files locally in a folder you simply use an FTP app to upload them.
By the way… I never use the Publish Site feature… I exclusely publish single pages or parent pages with sub-pages. If you set-up your parent pages and child pages well (in logical sections) this works great. You can publish single pages or entire sections easily. I never “Publish site.”
This works great for me… both for publishing (uploading) to the server and exporting to local folder.
