Linux kernel
============
The Linux kernel is the core of any Linux operating system. It manages hardware,
system resources, and provides the fundamental services for all other software.
Quick Start
-----------
* Report a bug: See Documentation/admin-guide/reporting-issues.rst
* Get the latest kernel: https://kernel.org
* Build the kernel: See Documentation/admin-guide/quickly-build-trimmed-linux.rst
* Join the community: https://lore.kernel.org/
Essential Documentation
-----------------------
All users should be familiar with:
* Building requirements: Documentation/process/changes.rst
* Code of Conduct: Documentation/process/code-of-conduct.rst
* License: See COPYING
Documentation can be built with make htmldocs or viewed online at:
https://www.kernel.org/doc/html/latest/
Who Are You?
============
Find your role below:
* New Kernel Developer - Getting started with kernel development
* Academic Researcher - Studying kernel internals and architecture
