-### Shape Theming
-
-Note: This documentation refers to legacy APIs that will eventually be deprecated. Please consider
-reading the updated [theming documentation](docs/theming.md) instead.
-
-You can theme buttons with your app's shape scheme using the ShapeThemer extension.
-
-You must first add the ShapeThemer extension to your project:
-
-```bash
-pod 'MaterialComponents/Buttons+ShapeThemer'
-```
-
-<!--<div class="material-code-render" markdown="1">-->
-#### Swift
-```swift
-// Step 1: Import the ShapeThemer extension
-import MaterialComponents.MaterialButtons_ShapeThemer
-
-// Step 2: Create or get a shape scheme
-let shapeScheme = MDCShapeScheme()
-
-// Step 3: Apply the shape scheme to your component
-MDCButtonShapeThemer.applyShapeScheme(shapeScheme, to: component)
-MDCFloatingButtonShapeThemer.applyShapeScheme(shapeScheme, to: component)
-```
-
-#### Objective-C
-
-```objc
-// Step 1: Import the ShapeThemer extension
-#import "MaterialButtons+ShapeThemer.h"
-
-// Step 2: Create or get a shape scheme
-id<MDCShapeScheming> shapeScheme = [[MDCShapeScheme alloc] init];
-
-// Step 3: Apply the shape scheme to your component
-[MDCButtonShapeThemer applyShapeScheme:shapeScheme
-     toButton:component];
-[MDCFloatingButtonShapeThemer applyShapeScheme:shapeScheme
-     toButton:component];
