You're about to initialize a Firebase project in this directory:

  path/firebase/prject_name

Before we get started, keep in mind:

  * You are currently outside your home directory

? Which Firebase CLI features do you want to setup for this folder? Press Space to select features, then Enter to confirm your choices. Functions: Configure and deploy 
Cloud Functions

=== Project Setup

First, let's associate this project directory with a Firebase project.
You can create multiple project aliases by running firebase use --add, 
but for now we'll just set up a default project.

? Select a default Firebase project for this directory: [create a new project]

=== Functions Setup

A functions directory will be created in your project with a Node.js
package pre-configured. Functions can be deployed with firebase deploy.

? What language would you like to use to write Cloud Functions? JavaScript
? Do you want to use ESLint to catch probable bugs and enforce style? No
✔  Wrote functions/package.json
✔  Wrote functions/index.js
✔  Wrote functions/.gitignore
? Do you want to install dependencies with npm now? Yes
