ADR-0000 Use Architecture Decision Records

ADR-0000 Use Architecture Decision Records#

Context and Problem Statement#

How do we document and track architectural decisions made during the project lifecycle? We need a lightweight way to capture the context, options considered, and rationale behind significant technical choices.

Considered Options#

  • No formal documentation — rely on commit messages and code comments

  • Wiki pages — centralized documentation but disconnected from code

  • Architecture Decision Records (ADRs) — lightweight markdown files in the repository

Decision Outcome#

Chosen option: “Architecture Decision Records” because:

  • ADRs live alongside the code in version control

  • They provide a clear template for capturing context and rationale

  • Historical decisions remain accessible even as team members change

  • The numbered format creates a natural chronological log

  • Markdown format is easy to write and renders well in GitLab/GitHub
