 # TransitionHelper
 
-TODO: Fill in information about this experiment and how to get started here...
-
-## Custom Control
-
-You can inherit from an existing component as well, like `Panel`, this example shows a control without a
-XAML Style that will be more light-weight to consume by an app developer:
-
-> [!Sample TransitionHelperCustomSample]
-
-## Templated Controls
-
-The Toolkit is built with templated controls. This provides developers a flexible way to restyle components
-easily while still inheriting the general functionality a control provides. The examples below show
-how a component can use a default style and then get overridden by the end developer.
-
-TODO: Two types of templated control building methods are shown. Delete these if you're building a custom component.
-Otherwise, pick one method for your component and delete the files related to the unchosen `_ClassicBinding` or `_xBind`
-classes (and the custom non-suffixed one as well). Then, rename your component to just be your component name.
-
-The `_ClassicBinding` class shows the traditional method used to develop components with best practices.
-
-### Implict style
-
-> [!SAMPLE TransitionHelperTemplatedSample]
-
-### Custom style
-
-> [!SAMPLE TransitionHelperTemplatedStyleCustomSample]
-
-## Templated Controls with x:Bind
-
-This is an _experimental_ new way to define components which allows for the use of x:Bind within the style.

-### Implict style
