+## Decision
+
+[Briefly describe the decision made in "We will..." format. This section should be concise - it's a declaration of intent for implementers. Detailed reasoning belongs in other sections.]
+
+## Context
+
+[Describe the situation that calls for a decision. Focus on forces, constraints, and circumstances that led to needing this decision. Answer "What is the problem?" not "What's the solution?" Include:
+
+- Technical, business, and organizational context
+- Applicable requirements (functional and cross-functional)
+- Current state and why change is needed
+- Key stakeholders and their concerns]
+
+### Decision Criteria (Optional)
+
+[Explicit criteria for evaluating options, such as:
+
+- Performance requirements
+- Cost constraints
+- Security requirements
+- Maintainability needs
+- Time-to-market considerations]
+
+## Problem (Optional)
+
+[Clearly state the problem being addressed. What issue or opportunity requires this architectural decision?]
+
+## Decision in Details (Optional)
+
+[Describe in details the decision made, including:
+
+- Key technical details
+- Implementation approach
+- Timeline considerations
+- Who is responsible for implementation]
+
+### Decision Drivers (Optional)
+
+- [Driver 1: Key force or requirement influencing the decision]
+- [Driver 2: Another key consideration]
+- [...]
+
+## Options
+
+[Briefly list the considered options. Each option is numbered for easy reference, with the selected option marked clearly as `(SELECTED)`. Aim for 3-5 options minimum. Always include at least "do nothing" option. A detailed description of each option can be written in the Consequences section below.]
+
+1. (SELECTED) [Name of selected option]
+2. [Name of alternative option]
+3. [Name of alternative option]
+4. [Do nothing / Status quo option]
+
+## Consequences (Optional)
+
+### Option 1: [Name of option] (SELECTED)
+
+[Brief description of this option.]
+
+**Selected because:**
+
+- [Benefit 1 that led to selection]
+- [Benefit 2 that led to selection]
+
+**Selected despite:**
+
+- [Drawback 1 that we accept]
+- [Drawback 2 that we accept]
+
+**Risks and Mitigations:**
+
+- [Risk 1]
+  - [Mitigation strategy 1]
+- [Risk 2]
+  - [Mitigation strategy 2]
+
+**Failure Recovery:**
+[How will we recover if this option fails?]
+
+### Option 2: [Name of alternative option]
+
+[Brief description of this option.]
+
+**Rejected because:**
+
+- [Critical drawback 1 - reason for rejection]
+- [Critical drawback 2 - reason for rejection]
+
+**Rejected despite:**
+
+- [Potential benefit 1 we're giving up]
+- [Potential benefit 2 we're giving up]
+
+*(Repeat for additional options if applicable)*
+
+## Implementation Notes (Optional)
+
+[Any specific guidance for implementing this decision, including:
+
+- Required dependencies
+- Migration steps
+- Testing considerations
+- Failure Recovery / Rollback procedures]
+
+## Confirmation (Optional)
+
+[Describe how the implementation of this decision will be verified. Include:
+
+- Acceptance criteria
+- Testing approach
+- Automated verification methods]
+
+## Advice (Optional)
+
+[Raw, unfiltered contributions from people who offered advice. his section provides transparency into the decision process and serves as a learning resource.]
+
+- [Advice given] ([Advice-giver's name, role], YYYY-MM-DD)
