Error in Rollup section

In the Rollup section, a section is written:
For a complete setup example see this gist.
And the word /* see this gist. */

The error I receive:

Öffne den Rollup-Abschnitt der React-Leistungsdokumentation und überprüfe das verlinkte Rich Harris-Gist. Ersetze den Verweis auf das eingeschränkte Gist durch eine zugängliche Alternative und verifiziere anschließend, dass der Abschnitt die Leser nicht mehr auf die deaktivierte Seite verweist.
