Lesson 0 Feedback - Starting Folder Not Explained

[brian9888]

Following https://github.com/DataVisHub/gojs-course/blob/main/lessons/lesson-0-project-setup-and-intro.md
It is not explained that I need to download the files from https://github.com/DataVisHub/gojs-course/ and execute

npm run start

from the top level folder so that the package.json file is present.
Otherwise, the failure occurs:

c:\>npm run start
npm ERR! code ENOENT
npm ERR! syscall open
npm ERR! path C:\package.json
npm ERR! errno -4058
npm ERR! enoent ENOENT: no such file or directory, open 'C:\package.json'
npm ERR! enoent This is related to npm not being able to find a file.
npm ERR! enoent
