GiST docs

Hi,

we got a spare time (well, hope so) and
we'are about to document GiST interface - sort of guide with intro,
examples and programming notices. I think it's worth to include it
into documentation for 7.2 release. What's a procedure for
taking part in documentation project ? What should be a style
of such guide ? GiST is very powerful feature of postgres and many people
just don't know how to use it.
Regards,    Oleg
