 You can combine `bat` with `git diff` to view lines around code changes with proper syntax
 highlighting:
 ```bash
-git diff --name-only --diff-filter=d | xargs bat --diff
+batdiff() {
+    git diff --name-only --diff-filter=d | xargs bat --diff
+}
 ```
+If you prefer to use this as a separate tool, check out `batdiff` in [`bat-extras`](https://github.com/eth-p/bat-extras).
