# Prodogon

> A practical reference for DevOps, information security, and software engineering - written for people who build software with AI coding assistants. Every guide is answer-first: each section starts with the direct answer, so a single section can be retrieved and cited on its own. Each page includes a Quick Answer block, an FAQ with schema.org markup, and linked sources.

Prodogon is a free, independent reference for people who build software by prompting AI coding assistants. It covers DevOps (CI/CD, GitOps, Kubernetes, infrastructure as code, observability), Information Security (prompt injection, non-human identities, supply-chain security, the OWASP Top 10), and Software Engineering (vibe coding, spec-driven development, testing, Git, databases). Every article is written answer-first and self-contained so individual sections can be quoted and cited without reading the rest of the page.
