[Samba] helping out with documentation?

[Veronica Hill]

What would be the best way to help out with Documentation - like 
changing some of the bits in Samba by example or adding pointers to 
other chapters where John Terpstra has missed a step that another 
chapter covers?

I can't find any info on the website that shows me how to write in the 
docbook xml format - I haven't done that before, so I need some 
pointers.  Where can I find some?
