+=====================
+Linux Kernel Teaching
+=====================
+
+This is a collection of lectures and labs Linux kernel topics. The
+lectures focus on theoretical and Linux kernel exploration.
+
+
+The labs focus on device drivers topics and they resemble "howto"
+style documentation. Each topic has two parts:
+
+* a walk-through the topic which contains an overview, the main
+  abstractions, simple examples and pointers to APIs
+
+* a hands-on part which contains a few exercises that should be
+  resolved by the student; to focus on the topic at hand, the student
+  is presented with a starting coding skeleton and with in-depth tips
+  on how to solve the exercises
+
+This content is based on the `Operatings Systems 2
+<http://ocw.cs.pub.ro/courses/so2>`_ course from the Computer Science
+and Engineering Department, the Faculty of Automatic Control and
+Computers, University POLITEHNICA of Bucharest.
+
+You can get the latest version at http://github.com/linux-kernel-labs.
+
+To get started build the documentation from the sources:
+
+.. code-block:: c
+   
+   cd tools/teaching && make docs
+
+then point your browser at **Documentation/output/labs/index.html**.
