The docs at
http://docs.getchip.com/chip.html had build instructions because, at the time of writing and after trying to find a definitive solution, that seemed to be the most reliable way to install PureData vanilla 0.46. The easy way of `sudo apt-get install puredata` installed a much older version of PD.
Besides, you gotta cut a dude a break - documenting PureData installation in the main documentation for this SOC was not exactly a mandate. Also, note that the documentation is a github repo, so if there’s anything that seems vital or incorrect, you can make a pull request at
https://github.com/getchip/CHIP-Docs/ and we can roll in the changes.
