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.
The essential guides for interacting with the kernel's development community and getting your work upstream.

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 ReStructured Text format, or are simply too old.
