You'll need to create a .env.local file with your firebase settings:

REACT_APP_API_KEY=
REACT_APP_AUTH_DOMAIN=
REACT_APP_DATABASE_URL=
REACT_APP_PROJECT_ID=
REACT_APP_STORAGE_BUCKET=
REACT_APP_MESSAGING_SENDER_ID=

Then:

# Install dependencies
npm install

# Start the dev server
npm start

# Have fun!
echo "🎉🎉🎉"
