+# Use Markdown Any Decision Records
+
+## Context and Problem Statement
+
+We want to record any decisions made in this project independent whether decisions concern the architecture ("architectural decision record"), the code, or other fields.
+Which format and structure should these records follow?
+
+## Considered Options
+
+* [MADR](https://adr.github.io/madr/) 3.0.0 – The Markdown Any Decision Records
+* [Michael Nygard's template](http://thinkrelevance.com/blog/2011/11/15/documenting-architecture-decisions) – The first incarnation of the term "ADR"
+* [Sustainable Architectural Decisions](https://www.infoq.com/articles/sustainable-architectural-design-decisions) – The Y-Statements
+* Other templates listed at <https://github.com/joelparkerhenderson/architecture_decision_record>
+* Formless – No conventions for file format and structure
+
+## Decision Outcome
+
+Chosen option: "MADR 3.0.0", 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](https://doi.org/10.1109/TSE.1986.6312940).
+* MADR allows for structured capturing of any decision.
+* The MADR format is lean and fits our development style.
+* The MADR structure is comprehensible and facilitates usage & maintenance.
+* The MADR project is vivid.
