 ## Trouble Shooting
-#### Using tooltip within the modal (e.g. [react-modal](https://github.com/reactjs/react-modal))
+### Using tooltip within the modal (e.g. [react-modal](https://github.com/reactjs/react-modal))
 The component was designed to set a `<Reactooltip />` one place then use tooltip everywhere, but a lot of people stuck in using this component with modal, you can check the discussion [here](https://github.com/wwayne/react-tooltip/issues/130), the summarization of solving the problem is as following:
 
 1. Put `<ReactTooltip />` out of the `<Modal>`
 2. Use `React.rebuild()` when opening the modal
 3. If your modal's z-index happens to higher than the tooltip, use the attribute `class` to custom your tooltip's z-index
