You can adapt this file completely to your liking, but it should at least

The Linux Kernel documentation
|
|
==============================
|
|
|
|
This is the top level of the kernel's documentation tree. Kernel
|
|
documentation, like the kernel itself, is very much a work in progress;
|
|
that is especially true as we work to integrate our many scattered
|
|
documents into a coherent whole. Please note that improvements to the
|
|
documentation are welcome; join the linux-doc list at vger.kernel.org if
|
|
you want to help out.
|
|
|
|
Licensing documentation
|
|
-----------------------
|
|
|
|
The following describes the license of the Linux kernel source code
|
|
(GPLv2), how to properly mark the license of individual files in the source
|
|
tree, as well as links to the full license text.

User-oriented documentation
|
|
---------------------------
|
|
|
|
The following manuals are written for *users* of the kernel — those who are
|
|
trying to get it to work optimally on a given system.

Firmware-related documentation

|
|
platform firmwares.

Application-developer documentation
|
|
-----------------------------------

|

The user-space API manual gathers together documents describing aspects of
|
|
the kernel interface as seen by application developers.

Introduction to kernel development
|
|
----------------------------------
|
|
|
|
These manuals contain overall information about how to develop the kernel.
|
|
The kernel community is quite large, with thousands of developers
|
|
contributing over the course of a year. As with any large community,
|
|
knowing how things are done will make the process of getting your changes
|
|
merged much easier.

Kernel API documentation
|
|
------------------------
|
|
|
|
These books get into the details of how specific kernel subsystems work
|
|
from the point of view of a kernel developer. Much of the information here
|
|
is taken directly from the kernel source, with supplemental material added
|
|
as needed (or at least as we managed to add it — probably *not* all that is
|
|
needed).
