how to document database

I need to document the  database I develop so that other people can
easily understand how it works.

I particularly want to document the stored procedures. By now I've used
a javadoc style to document them. I can't use tools like doxygen on them
but it is always better than nothing.

I'd like to know if you're using some particular tool.

Thanks
