This is a modern/modified version of the "Brokenthorn Entertainment - OS Development Series" (http://www.brokenthorn.com/Resources/OSDevIndex.html) which is a series of step by step tutorials aimed at those beginning systems development. This is static site documentation generated using DocFX (https://dotnet.github.io/docfx/)
There are tables which have colspans and stuff which have been put in code boxes to solve the problem of rendering them.
They have to be made exact markdown tables using DFM/ ms docs FM.
e.g.: article: IA32 Machine Language
setup github issues for forum like discussions like the framework used by docs.microsoft.com
Check if it is actually possible for static sites, or maybe it is coming up as part of DocFX V3
