🎯 Quick Start Guide

For Developers New to the API

1. Read this first (5 minutes):

less API_QUICK_REFERENCE.md

2. Run a test (1 minute):

# Start server
python3 imu_api_server.py

# Test in another terminal
curl http://localhost:5000/api/imu-data

3. Dive deeper (30 minutes):

less API_DOCUMENTATION.md
# Focus on sections:
# - Architecture
# - REST API Endpoints
# - Client Libraries (your language)

For Integration Testing

1. Review OpenAPI spec:

cat openapi.yaml

2. Run test suite:

python3 test_imu_api_server.py

3. Generate client (optional):

# Python client
openapi-generator-cli generate -i openapi.yaml -g python -o ./python-client

# JavaScript client
openapi-generator-cli generate -i openapi.yaml -g javascript -o ./js-client

For Production Deployment

1. Read deployment section:

# In API_DOCUMENTATION.md, go to "Deployment" section
grep -A 50 "## Deployment" API_DOCUMENTATION.md

2. Configure logging:

# Review logging configuration
grep -A 20 "Configure logging" imu_api_server.py

3. Set up monitoring:

# Add health check to your monitoring system
curl http://localhost:5000/api/imu-data
