-The **long text tooltip** component is a tooltip that can be used to display long text to users. It uses the `Tooltip` component to display the truncated text passed in as `content`. It uses  `maxLength` prop to control the size of the content, and the `Tooltip` component to display the rest of the content.
+The **long-text tooltip** component enables you to display long text to users via a tooltip. It builds off of the [tooltip component](https://www.patternfly.org/components/tooltip) to truncate UI text in an element and display the truncated text in a tooltip. 
 
 ## Examples
 
-### LongTextTooltip component
+### Basic long-text tooltip
 
-To provide users with long text, a basic long text tooltip should contain an appropriate and informative `content` and `maxLength`.  Additionally you can pass in a `tooltipPosition` to control the position of the tooltip, and `tooltipMaxWidth` to control the tool tip width.
+To show users the full value of truncated content, a basic long-text tooltip should contain appropriate and informative `content` and specify the `maxLength` of the UI text (after which, truncation will occur).  
+
+Additionally you can pass in a `tooltipPosition` to control the position of the tooltip, and `tooltipMaxWidth` to control the tooltip width.
