==============================
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.
Working with the development community
======================================
The essential guides for interacting with the kernel's development
community and getting your work upstream.
.. toctree::
:maxdepth: 1
Development process <process/development-process>
Submitting patches <process/submitting-patches>
Code of conduct <process/code-of-conduct>
Maintainer handbook <maintainer/index>
All development-process docs <process/index>
Internal API manuals
====================
Manuals for use by developers working to interface with the rest of the
kernel.
.. toctree::
:maxdepth: 1
Core API <core-api/index>
Driver APIs <driver-api/index>
Subsystems <subsystem-apis>
Locking <locking/index>
Development tools and processes
===============================
Various other manuals with useful information for all kernel developers.
.. toctree::
:maxdepth: 1
Licensing rules <process/license-rules>
Writing documentation <doc-guide/index>
Development tools <dev-tools/index>
Testing guide <dev-tools/testing-overview>
Hacking guide <kernel-hacking/index>
Tracing <trace/index>
Fault injection <fault-injection/index>
Livepatching <livepatch/index>
Rust <rust/index>
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 and application
developers seeking information on the kernel's user-space APIs.
.. toctree::
:maxdepth: 1
Administration <admin-guide/index>
Build system <kbuild/index>
Reporting issues <admin-guide/reporting-issues.rst>
Userspace tools <tools/index>
Userspace API <userspace-api/index>
See also: the `Linux man pages <https://www.kernel.org/doc/man-pages/>`_,
which are kept separately from the kernel's own documentation.
Firmware-related documentation
==============================
The following holds information on the kernel's expectations regarding the
platform firmware.
.. toctree::
:maxdepth: 1
Firmware <firmware-guide/index>
Firmware and Devicetree <devicetree/index>
Architecture-specific documentation
===================================
.. toctree::
:maxdepth: 2
CPU architectures <arch/index>
Other documentation
===================
There are several unsorted documents that don't seem to fit on other parts
of the documentation body, or may require some adjustments and/or conversion
to reStructuredText format, or are simply too old.
.. toctree::
:maxdepth: 1
Unsorted documentation <staging/index>
