+## Definition
+Architecture Decision Record（架构决策记录）是一种轻量级文档，用于捕获架构决策的上下文、选项和理由。ADR 记录的是"为什么这样做"，而不仅仅是"做了什么"。
+
+## ADR Format
+
+```markdown
+# ADR-001: [Decision Title]
+
+## Status
+Proposed | Accepted | Deprecated | Superseded by ADR-XXX
+
+## Context
+What is the issue that we're seeing that is motivating this decision?
+
+## Decision
+What is the change that we're proposing and/or doing?
+
+## Consequences
+What becomes easier or harder because of this change?
+```
+
+## Key Elements
+- **Status**：Proposed（提议中）/ Accepted（已接受）/ Deprecated（已废弃）/ Superseded（被替代）
+- **Context**：驱动决策的问题或背景
+- **Decision**：具体的决策内容
+- **Consequences**：决策的后果——什么变得更容易，什么变得更难
+
+## Core Principles
+- **记录 WHY，而非 WHAT**：代码已经说明了"做了什么"，ADR 应该说明"为什么这样做"
+- **可追溯性**：随着系统演进，ADR 提供了决策的历史脉络
+- **知识共享**：新成员可以通过 ADR 理解架构决策的背景
