1. You have to register a GitHub application first:
   • Homepage URL = http://localhost:9001
   • Authorization callback URL = http://localhost:9001/callback
2. Then save these two files in a new directory.
3. Then take the "Client ID" and "Client Secret" values and fill in the blanks in your shell:

GITHUB_CLIENT=_____ GITHUB_SECRET=_____ npm install
