Use Markdown Architectural Decision Records

Should we record the architectural decisions made in this project? And if we do, how to structure these recordings?

Considered Options

Use MADR 1.4.0 - The Markdown Architectural Decision Records
Michael Nygard's template - The first incarnation of the term "ADR". Maintainable by adr-tools.
Sustainable Architectural Decisions - The Y-Statements
Other templates listed at https://github.com/joelparkerhenderson/architecture_decision_record
No records

Decision Outcome

Chosen option: MADR 1.4.0, because:

Implicit assumptions should be made explicit. Design documentation is important to enable people understanding the decisions later on. See also A rational design process: How and why to fake it.
The MADR template is lean and fits our development style.
Version 1.4.0 is the latest one available when starting to document ADRs.
