### Markdown Architectural Decision Records (MADR)
## Markdown Architectural Decision Records (MADR)

MADR is about architectural decisions that *matter* ([`[ˈmæɾɚ]`](https://en.wiktionary.org/wiki/matter#Pronunciation)). You can read more about MADR [here](https://www.ozimmer.ch/practices/2022/11/22/MADRTemplatePrimer.html). You can use MADR without installing software by populating the template in any text editor. Additionally, a [VS Code extension](https://marketplace.visualstudio.com/items?itemName=StevenChen.vscode-adr-manager) is available, though it may be outdated and lack support for the latest features. [Other tools](https://adr.github.io/adr-tooling/#madr-template) are also available.

Olaf Zimmermann's [MADR Template Primer](https://www.ozimmer.ch/practices/2022/11/22/MADRTemplatePrimer.html) covers it in more depth.

Rationale for this decision is available [here](https://github.com/adr/madr/tree/4.0.0/template#decisions).

The rationale for this decision is documented in the [template decisions](https://github.com/adr/madr/tree/4.0.0/template#decisions).

We think that the *considered options* with their pros and cons are crucial to understand the reasons for choosing a particular design. Therefore, the [Markdown Architectural Decision Records (MADR)](https://adr.github.io/madr/) project in this organization includes such tradeoff analysis information. It also suggests metadata such as decision makers and confirmation in addition to decision status.

### Nygard ADR
## Nygard ADR

An ADR consists of title, status, context, decision, and consequences according to "Documenting Architecture Decisions" by [@mtnygard](https://github.com/mtnygard). <!-- From the Nygard post: "Context This section describes the forces at play, including technological, political, social, and project local." and "We should use a lightweight text formatting language like Markdown or Textile." -->

The blog post from 2011 that suggests this structure is [here](https://cognitect.com/blog/2011/11/15/documenting-architecture-decisions) and a Markdown rendering of it is available [here](https://github.com/joelparkerhenderson/architecture-decision-record/blob/main/locales/en/templates/decision-record-template-by-michael-nygard/index.md).
