+# Architecture Decision Records
+
+This directory tracks Architecture Decision Records (ADRs) for **test-argocd-gitops-c6**.
+
+ADRs capture the context, trade-offs, and consequences of significant technical choices. They are lightweight documents — typically one to two pages — following the [MADR format](https://adr.github.io/madr/).
+
+## Why ADRs?
+
+- **Preserve context**: Future engineers understand *why* a decision was made, not just what was decided.
+- **Reduce re-litigation**: A documented decision stops teams re-debating the same trade-offs every quarter.
+- **Accelerate onboarding**: New team members read ADRs to understand the service's evolution without archaeology.
+
+## Index
+
+| # | Title | Status | Date |
+|---|-------|--------|------|
+| *(add entries here as ADRs are created)* | | | |
+
+## Creating a new ADR
+
+1. Copy the template below into `docs/adr/NNNN-<short-title>.md` where `NNNN` is the next sequential number.
+2. Fill in every section — even if the answer is "not applicable, because...".
+3. Open a pull request so the team can review the decision **before** it is finalized.
+4. Update the index table above once the ADR is accepted.
+
