+Inheritance
+-----------
+
+You can easily create multiple factories for the same class without repeating common attributes by nesting factories:
+
+```ruby
+factory :post do
+  title "A title"
+
+  factory :approved_post do
+    approved true
+  end
+end
+
+approved_post = create(:approved_post)
+approved_post.title    # => "A title"
+approved_post.approved # => true
+```
+
+You can also assign the parent explicitly:
+
+```ruby
+factory :post do
+  title "A title"
+end
+
+factory :approved_post, parent: :post do
+  approved true
+end
+```
+
+As mentioned above, it's good practice to define a basic factory for each class
+with only the attributes required to create it. Then, create more specific
+factories that inherit from this basic parent. Factory definitions are still
+code, so keep them DRY.
