Documentation is not one of the favorite tasks in the everyday software development. Either there is hardly any documentation or too much. This makes it difficult to find information. A lightweight approach is the arc42 template. It also documents design decisions that shape the software architecture. Undocumented design decisions can lead to incorrect follow-up decisions that can cause the project to fail. But how can many decisions be documented efficiently and comprehensibly? This presentation will introduce a compact format called Architecture Decision Records (ADR) and show how they can be used efficiently. In addition to small details such as title assignment, a proposed solution is shown for dealing with a large collection of design decisions (>50). The Docs As Code approach is used. Through tagging and an efficient search, the documentation becomes a daily work tool.
