# Windmill - Developer Infrastructure Platform
# https://github.com/windmill-labs/windmill
#
# Windmill is an open-source developer platform and workflow engine that allows you to
# quickly build production-grade multi-step automations and internal apps from minimal
# scripts in Python, TypeScript, Go, Bash, SQL, or any Docker image.
#
# Key Features:
# - Write scripts in Python, TypeScript, Go, Bash, SQL
# - Auto-generated UIs from scripts
# - Visual workflow builder with code execution
# - Built-in scheduling and webhooks
# - Version control and audit logs
# - Multi-tenant workspaces
#
# Default Credentials:
# - Access UI at http://localhost:8000
# - Default email: admin@windmill.dev
# - Default password: changeme
#
# Security Notes:
# - Change default admin credentials immediately
# - Use strong database passwords
# - Enable SSL/TLS in production
# - Configure proper authentication (OAuth, SAML)
