Below is an assemblage of resources for Miller Puckette's graphical programming enviroment, PureData or PD.  The list of items will grow as time goes by and as new items become available.  The PD community is, by philosophy, inclined to freely contribute to its development, offering their own insights back to the community of users.  Feel free to avail yourself of the rescources beyond documentation such as the mailing lists and "pd webring" pages and become a contributing community member yourself.
