This is based on an earlier blog post at people.kernel.org, it describes the concepts about page tables that were hardest for me to grasp when dealing with them for the first time, such as the prevalent three-letter acronyms pfn, pgd, p4d, pud, pmd and pte. I don't know if this is what people want, but it's what I would have wanted. The wording, introduction, choice of initial subjects and choice of style is mine. I discussed at one point with Mike Rapoport to bring this into the kernel documentation, so here is a small proposal. The current form is augmented in response to feedback from Mike Rapoport, Matthew Wilcox, Jonathan Cameron, Kuan-Ying Lee, Randy Dunlap and Bagas Sanjaya.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
