Palette Builder usage instructions do not work

[ap-1]

npm install fails with the following error:

npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path /home/DIRECTORY/toolbox/package.json
npm ERR! errno -2
npm ERR! enoent ENOENT: no such file or directory, open '/home/DIRECTORY/toolbox/package.json'
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent 

This is due to the main directory not having a package.json. It can be avoided by navigating to the palette builder directory before running npm install.
