-## 💡 Plugin Development Tips
+## 💡 Important
 
-To ensure your plugin is correctly recognized and published:
-- Include complete metadata (Frontmatter):
-  ```python
-  """
-  title: Plugin Name
-  author: Your Name
-  version: 0.1.0
-  description: Short description
-  """
-  ```
-- If updating an existing plugin, remember to **increment the version number** (e.g., `0.1.0` -> `0.1.1`). Our CI will automatically sync it to the OpenWebUI Community.
+- Ensure your plugin includes complete metadata (title, author, version, description).
+- If updating an existing plugin, please **increment the version number** (e.g., `0.1.0` -> `0.1.1`) to trigger the auto-update.
