My favourite site for navigating and reading the source is: http://lxr.linux.no/ I think that should help you a lot with "reading the kernel". Reading the source is sometimes the better documentation and, of course, you will have to look things up. If you are interested in device drivers you should try: http://lwn.net/Kernel/LDD3/ or Essential Linux Device Drivers, by Sreekrishnan Venkateswaran > Another thing is that I'm not sure which area of the kernel I'd like > to contribute to.

I think a good idea to start with would be to write a simple kernel module, e.g. a device driver that lets your keyboard LEDs blink or sth like that, just to get into it. Another thing which I started with was to write a very simple VFS filesystem that helped me getting to know how these things work. For some more C having a look into this book is also quite helpful: http://publications.gbdirect.co.uk/c_book/ Good luck :) Cheers, Daniel
