What problem does it solve?
Architecture Decision Records (ADRs) provide a structured way to capture significant technical decisions, their context, rationale, and trade-offs so teams can learn from past choices and maintain architectural alignment over time.
ADRs enable a consistent approach to documenting decisions, making it easier to onboard new engineers, review past rationale during refactors, and track how architecture evolves.
Core Features & Use Cases
- Standardized ADR templates that enforce a consistent file structure (adr-NNN-title.md) and frontmatter with name and description.
- Traceability & rationale: captures the problem context, proposed alternatives, trade-offs, decisions, and outcomes for auditability.
- Guidance for governance: supports team adoption with naming conventions, directory layout, and review workflows.
Quick Start
- Identify the architectural decision to capture and determine the next ADR number.
- Create a new file under docs/architecture-decisions/ with the name adr-NNN-title.md following the ADR template.
- Populate the frontmatter with name and description and fill out Problem, Alternatives, Decision, Implementation, and Future Considerations sections.
