Installation instructions are in the HTML DOCUMENTATION at: http://www.crca.ucsd.edu/~msp/Pd_documentation/index.htm If you download and unpack Pd, you will also find the html documentation locally in the file, .../pd-whatever/doc/1.manual/index.htm. To unpack Pd: LINUX (or freeBSD). In some linux installations you can download Pd via "apt-get install puredata" or "yum install puredata"; otherwise you will have to download the source and compile it as described in the file, INSTALL.txt Microsoft Windows. Pd binaries are distributed as a "zip" file. Unzip this, creating a directory such as \pd. Macintosh. The web browser will automatically unpack the distributions into a folder such as "pd-0.35" on your desktop.
