Linux Kernel

There are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. Please read Documentation/admin-guide/README.rst first.

In order to build the documentation, use make htmldocs or make pdfdocs. The formatted documentation can also be read online at Kernel Organization.

There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation.

See Documentation/00-INDEX for a list of what is contained in each file.

Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result from upgrading your kernel.

For more information, visit Linux in GitHub.
