+
+IDEs and editors that support Dart usually provide easy ways to run the
+formatter. For example, in WebStorm you can right-click a .dart file and then
+choose **Reformat with Dart Style**.
+
+Here's a simple example of using the formatter on the command line:
+
+    $ dart format test.dart
+
+This command formats the `test.dart` file and writes the result to the
+file.
+
+`dart format` takes a list of paths, which can point to directories or files. If
+the path is a directory, it processes every `.dart` file in that directory or
+any of its subdirectories.
+
+By default, it formats each file and write the formatting changes to the files.
+If you pass `--output show`, it prints the formatted code to stdout.
+
+You may pass a `-l` option to control the width of the page that it wraps lines
+to fit within, but you're strongly encouraged to keep the default line length of
+80 columns.
+
+### Validating files
+
+If you want to use the formatter in something like a [presubmit script][] or
+[commit hook][], you can pass flags to omit writing formatting changes to disk
+and to update the exit code to indicate success/failure:
+
+    $ dart format --output=none --set-exit-if-changed .

-Here's a simple example of using dartfmt on the command line:

-Dartfmt takes a list of paths, which can point to directories or files. If the

-standard input.

-By default, it formats each file and just prints the resulting code to stdout.
-If you pass `-w`, it overwrites your existing files with the formatted results.

-formatter prints the paths of the files whose contents would change if the
-formatter were run normally. If it prints no output, then everything is already
-correctly formatted.
