## What it is
The canonical repository for the updated text of the Twelve-Factor Manifesto, a methodology for building modern, cloud-native SaaS applications. It is a documentation project (CC-BY-4.0) that will ultimately replace 12factor.net.

## Use cases
- learn the twelve-factor methodology for building SaaS apps
- read the updated twelve-factor manifesto
- understand best practices for cloud-native application design
- reference guidelines for deployable, scalable services
- contribute to or track revisions of the twelve-factor principles

## When to choose
- you want authoritative, community-governed guidance on twelve-factor app principles
- you are designing cloud-native or SaaS applications and need a methodology reference
- you want the most current revision of the manifesto rather than the legacy 12factor.net site

## When to avoid
- you need executable tooling or code rather than a written methodology
- you want a finished, frozen document — this is an actively evolving update
- you need platform-specific implementation tutorials

## Facets

- maturity: active
- function: documentation
- domain: developer-tools, cloud-computing, tutorials
