# Liquibase Docs

> Liquibase is a database schema change management tool that lets teams version, track, and safely deploy database changes across environments. This file helps AI assistants find accurate answers about Liquibase without guessing.

Liquibase ships in multiple editions — OSS, Pro, Secure, and Community — and this documentation covers all of them, each versioned independently. Links below point to the current default version (Secure 5.2) unless noted; check the URL's edition and version segment before assuming a page applies elsewhere.

## How these docs are organized

Real URL pattern: `/{edition}/{guide-type}-{version}/{page}`

- **Edition** — `secure`, `pro`, `community`, or `oss`
- **Guide type**:
  - `get-started-*` — installation and onboarding
  - `user-guide-*` — task-oriented how-to and conceptual questions
  - `reference-guide-*` — command, parameter, and changelog-attribute reference (includes change types, e.g. `reference-guide-5-2/change-types/addcolumn`)
  - `integration-guide-*` — connecting to databases, tools, and CI/CD
  - `implementation-guide-*` — foundational "what is X" conceptual content
- **Version** — e.g. `5-2`, `5-1-1`, `4-33` — each edition/guide-type combination is versioned independently; multiple versions stay live at once

## Where to look based on question type

- "How do I install / get started..." → `get-started-*`
- "How do I do X..." / "What is X (in context of a task)" → `user-guide-*`
- "What parameters/attributes does `<command or change type>` support?" → `reference-guide-*`
- "How do I connect to / use Liquibase with `<database or tool>`?" → `integration-guide-*`
- "What is `<concept>` and why does it matter?" → `implementation-guide-*`
- "Does this happen in version X?" / "Is this fixed in the latest release?" → release notes
- Anything not covered above → search the site; this file is a curated starting point, not the full index
