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.

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.

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.
