A simple Address Book app I made while learning Node.js;
1. Open the terminal window and navigate to the project folder; 2. Type "npm install -g" to install the app; 3. Type "contacts add name,number" to add a contact (where name and number are the ones from the contact); 4. Type "contacts find name" to find a contact (where name is the name of the contact you're looking for);This is a simple app. It will store all his data in a single JSON file in the user's home folder.
