# Notes
|
|
# ======================
|
|
# - SQLite is perfect for development and testing (no setup required!)
|
|
# - Use PostgreSQL for production deployments
|
|
# - Never commit the actual .env file to version control
|
|
# - Use strong, unique secrets in production
|
|
# - Keep your LNbits keys secure
|
|
# - Test with small amounts first
