+
+## Testing Plan
+>How should the component be tested?
+
+## Trade-offs and Potential Problems
+>Write down any conscious trade-off you made that can be problematic in the future, or any problems discovered during the design process that remain unaddressed (technical debts).
+
+## Glossary (Optional)
