            React components implement a render() method that takes input data
            and returns what to display. This example uses an XML-like syntax
            called JSX. Input data that is passed into the component can be
            accessed by render() via this.props. JSX is optional and not
            required to use React.
          </MatchText>
        </p>
      </SearchProvider>
    );
  }
