+<type>[optional scope]: <description>
 
-<detailed description, wrapped at 72 chars>
+[optional body]
 
-Impact: <user-visible effects or context for future release notes>
+[optional footer(s)]
 ```
 
-**Best Practices:**
+**Required Elements:**
 
--   **Subject line**: Max 50 chars (hard limit 72), imperative mood ("Add" not "Added")
--   **Body**: Wrap at 72 chars, explain WHAT and WHY (not HOW - code shows that)
--   **Blank line**: Required between subject and body
--   **Impact section**: Our addition for release note generation (optional but recommended)
+-   **type**: Lowercase, communicates intent (feat, fix, docs, etc.)
+-   **description**: Short summary (max 50-72 chars), imperative mood ("add" not "added"), lowercase start, no period
 
-**Types:**
+**Optional Elements:**
+
+-   **scope**: Parentheses after type, e.g., `feat(sensors):` - lowercase, specific area of change
+-   **body**: Detailed explanation, wrap at 72 chars, explain WHAT and WHY (not HOW - code shows that)
+-   **footer**: Breaking changes, issue references, or custom fields
+
+**Breaking Changes:**
+
+Use `BREAKING CHANGE:` footer or `!` after type/scope:
+```
+feat(api)!: drop support for legacy endpoint

+```
+
