+.. The Linux Kernel documentation master file, created by

+
+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.
+
+Licensing documentation
+-----------------------
+
+The following describes the license of the Linux kernel source code
+(GPLv2), how to properly mark the license of individual files in the source
+tree, as well as links to the full license text.

+
+User-oriented documentation
+---------------------------
+
+The following manuals are written for *users* of the kernel — those who are
+trying to get it to work optimally on a given system.

+Application-developer documentation
+-----------------------------------
+
+The user-space API manual gathers together documents describing aspects of
+the kernel interface as seen by application developers.

+
+Introduction to kernel development
+----------------------------------
+
+These manuals contain overall information about how to develop the kernel.
+The kernel community is quite large, with thousands of developers
+contributing over the course of a year. As with any large community,
+knowing how things are done will make the process of getting your changes
+merged much easier.

+Kernel API documentation
+------------------------
+
+These books get into the details of how specific kernel subsystems work
+from the point of view of a kernel developer. Much of the information here
+is taken directly from the kernel source, with supplemental material added
+as needed (or at least as we managed to add it — probably *not* all that is
+needed).
