+Customizing Seed and Migration templates
+----------------------------------------
+
+Because migrations uses `bake <https://book.cakephp.org/bake>`__ under the hood
+you can customize the templates that migrations uses for creating seeds and
+migrations by creating templates in your application. Custom templates for
+migrations should be on one of the following paths:
+
+- ``ROOT/templates/plugin/Migrations/bake/``
+- ``ROOT/templates/bake/``
+
+For example the seed template is ``Seed/seed.twig`` and its full path would be
+**ROOT/templates/plugin/Migrations/bake/Seed/seed.twig**
