+[![build status](https://travis-ci.org/angel-dart/seeder.svg?branch=master)](https://travis-ci.org/angel-dart/seeder)
+
+Straightforward data seeder for Angel services.
+This is an almost exact port of [feathers-seeder](https://github.com/thosakwe/feathers-seeder),
+so its documentation should almost exactly match up here.
+Fortunately, I was also the one who made `feathers-seeder`, so if you ever need assistance,
+file an issue. 
+
+# Example
+```dart
+var app = new Angel()..use('/todos', new TodoService());
+
+await app.configure(seed(
+    'todos',
+    new SeederConfiguration<Todo>(delete: false, count: 10, template: {
+        'text': (Faker faker) => 'Clean your room, ${faker.person.name()}!',
+        'completed': false
+    })));
+```
+
+**NOTE**: Don't *await* seeding at application startup; that's too slow.
+Instead, run it asynchronously.
