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 COPYINGDocumentation 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* Security Expert - Hardening and vulnerability analysis* Backport/Maintenance Engineer - Maintaining stable kernels* System Administrator - Configuring and troubleshooting* Maintainer - Leading subsystems and reviewing patches* Hardware Vendor - Writing drivers for new hardware* Distribution Maintainer - Packaging kernels for distrosFor Specific Users==================New Kernel Developer--------------------Welcome!
