Index of Further Kernel Documentation
=====================================

The need for a document like this one became apparent in the linux-kernel
mailing list as the same questions, asking for pointers to information,
appeared again and again.

Fortunately, as more and more people get to GNU/Linux, more and more get
interested in the Kernel. But reading the sources is not always enough. It
is easy to understand the code, but miss the concepts, the philosophy and
design decisions behind this code.

Unfortunately, not many documents are available for beginners to start.
And, even if they exist, there was no "well-known" place which kept track
of them. These lines try to cover this lack.

PLEASE, if you know any paper not listed here or write a new document,
include a reference to it here, following the kernel's patch submission
process. Any corrections, ideas or comments are also welcome.

All documents are cataloged with the following fields: the document's
"Title", the "Author"/s, the "URL" where they can be found, some "Keywords"
helpful when searching for specific topics, and a brief "Description" of
the Document.

.. note::

   The documents on each section of this document are ordered by its
   published date, from the newest to the oldest. The maintainer(s) should
   periodically retire resources as they become obsolete or outdated; with
   the exception of foundational books.
