"""🏃‍♂️ Simple Garmin Connect API Example.
=====================================

This example demonstrates the basic usage of python-garminconnect:
- Authentication with email/password
- Token storage and automatic reuse
- MFA (Multi-Factor Authentication) support
- Comprehensive error handling for all API calls
- Basic API calls for user stats

For a comprehensive demo of all available API calls, see demo.py

Dependencies:
pip3 install garth requests

Environment Variables (optional):
export EMAIL=<your garmin email address>
export PASSWORD=<your garmin password>
export GARMINTOKENS=<path to token storage>
