 - If your website is **mostly static** (for example, a portfolio or a blog), consider using [Gatsby](https://www.gatsbyjs.org/) or [Next.js](https://nextjs.org/). Unlike Create React App, Gatsby pre-renders the website into HTML at build time. Next.js supports both server rendering and pre-rendering.
 
-- Finally, if you need **more customization**, check out [Neutrino](https://neutrino.js.org/) and its [React preset](https://neutrino.js.org/packages/react/).
-
 All of the above tools can work with little to no configuration.
 
 If you prefer configuring the build yourself, [follow this guide](https://reactjs.org/docs/add-react-to-a-website.html).
