+## Directory contents
+
+The `.yaml` files in these directories are used to
+define the [`dart fix` framework](https://dart.dev/tools/dart-fix) refactorings
+used by the Flutter framework.
+
+The number of fix rules defined in a file should not exceed 50 for better
+maintainability. Searching for `title:` is a given `.yaml` file will account
+for the number of fixes. Splitting out fix rules should be done by class.
+
+When adding a new `.yaml` file, make a copy of `fix_template.yaml`. If the new
+file is not for generic library fixes (`fix_material.yaml`), ensure it is
+enclosed in an appropriate library directory (`fix_data/fix_material`), and
+named after the class. Fix files outside of generic libraries should represent
+individual classes (`fix_data/fix_material/fix_app_bar.yaml`).
+
+See the flutter/packages/flutter/test_fixes directory for the tests that
+validate these fix rules.
+
+To run these tests locally, execute this command in the
+flutter/packages/flutter/test_fixes directory.
+```sh
+dart fix --compare-to-golden
+```
+
+For more documentation about Data Driven Fixes, see
+https://dart.dev/go/data-driven-fixes#test-folder.
+
+To learn more about how fixes are authored in package:flutter, see
+https://github.com/flutter/flutter/wiki/Data-driven-Fixes
+
+## When making structural changes to this directory
+
+Note that the tests in this directory are also invoked from external
+repositories. Specifically, the CI system for the dart-lang/sdk repo runs these
+tests in order to ensure that changes to the dart fix file format do not break
+Flutter.
+
+See [tools/bots/flutter/analyze_flutter_flutter.sh](https://github.com/dart-lang/sdk/blob/main/tools/bots/flutter/analyze_flutter_flutter.sh)
+for where the tests are invoked.
+
+When possible, please coordinate changes to this directory that might affect the
+`analyze_flutter_flutter.sh` script.
