-   ```
-   # Learn and use repository-wide commit style
+5. **Custom Styles**
+   ```bash
+   # Learn from repository history
    auto-commit --learn

-6. **Author-Specific** (`--learn --author`): Learn and use a specific author's commit style
-   ```
-   # Learn and use commit style from specific author
+
+   # Learn from specific author
    auto-commit --learn --author="[email protected]"
    ```
+   The tool can learn and adopt commit styles from your repository's history or a specific author's commits.
 
-The learned styles (both repository and author-specific) are saved and will be used for future commits unless overridden with the `--format` flag.
+Override the format using `--format`:
+```bash
+auto-commit --format conventional  # default
+auto-commit --format angular      # Angular style
+auto-commit --format semantic     # with emojis
+auto-commit --format kernel       # Linux style
+```
