+# Clipboard
+
+Clipboard gives you an interface for setting to the clipboard. (Getting
+clipboard content is not supported on web.)
+
+## Methods
+
+static **getString**()
+
+Returns a `Promise` of an empty string.
+
+static **setString**(content: string): boolean
+
+Copies a string to the clipboard. On web, some browsers may not support copying
+to the clipboard, therefore, this function returns a boolean to indicate if the
+copy was successful.

+# Button
+
+A basic button component. Supports a minimal level of customization. You can
+build your own custom button using `TouchableOpacity` or
+`TouchableNativeFeedback`.
+
+## Props
+
+**accessibilityLabel**: string
+
+Defines the text available to assistive technologies upon interaction with the
+element. (This is implemented using `aria-label`.)
+
+**color**: string
+
+Background color of the button.
+
+**disabled**: bool = false
+
+If true, disable all interactions for this component
+
+**onPress**: function
+
+This function is called on press.
+
+**title**: string
+
+Text to display inside the button.
+
+## Examples
+
+```js
+<Button
+  accessibilityLabel="Learn more about this purple button"
+  color="#841584"
+  onPress={onPressLearnMore}
+  title="Learn More"
