+=============================================
+Working with the kernel development community
+=============================================
+
+So you want to be a Linux kernel developer?  Welcome!  While there is a lot
+to be learned about the kernel in a technical sense, it is also important
+to learn about how our community works.  Reading these documents will make
+it much easier for you to get your changes merged with a minimum of
+trouble.
+
+An introduction to how kernel development works
+-----------------------------------------------
+
+Read these documents first: an understanding of the material here will ease
+your entry into the kernel community.

+Tools and technical guides for kernel developers
+------------------------------------------------
+
+This is a collection of material that kernel developers should be familiar
+with.

+Policy guides and developer statements
+--------------------------------------
+
+These are the rules that we try to live by in the kernel community (and
+beyond).

+Dealing with bugs
+-----------------
+
+Bugs are a fact of life; it is important that we handle them properly. The
+documents below provide general advice about debugging and describe our
+policies around the handling of a couple of special classes of bugs:
+regressions and security problems.
