how to access the main page of abaqus-docs.mit.edu

I found a great tutorial for abaqus/cae at https://abaqus-docs.mit.edu/2017/English/SIMACAEGSARefMap/simagsa-m-Caeb... but I cannot find the main page, which I need to navigate it; I am forced to Google for individual sections guessing at what the section titles migh be; I need a URL to the root page so I can navigate the tutorial like an ebook.
