Hi Sampson,
I don’t recall exactly how I showed the guide section in that video, sorry. To get the correct wording for the Guide section your best bet is to follow the most recent Publisher Guidelines for the device (e.g. Kindle Publishing Guidelines) and see what they say.
But in general, I’d say yes, you can use the same markup I showed, just make sure you use the correct path to the target document in your ebook.
I do know that the Guide section is for EPUB 2. If you’re exporting to EPUB 3, the Landmarks section at the end of the toc.xhtml is where you put that info:
The recommended method is to provide a landmark like this in the navigation document:
https://www.idpf.org/accessibility/guidelines/content/nav/landmarks.php
If you’re using InDesign CC 2014, you use the Object Export Options dialog’s epub:type menu to specify these elements, and InDesign will automatically include the landmarks (in EPUB 3) and the guide (in EPUB 2).
Also in InDesign CC 2014, you don’t need to specify where the cover is or where the in-book TOC is, it’ll pick that up and the info to landmarks/guide automatically.
hope that helps!
AM
