# Add React Helmet
React Helmet is a reusable React component that manages all of your changes to the document head.
Helmet takes plain HTML tags and outputs plain HTML tags.
[gatsby-plugin-helmet](https://www.gatsbyjs.org/packages/gatsby-plugin-react-helmet/?=react%20helmet) makes it easy to use React Helmet inside Gatsby projects as it automatically adds title and meta tags to the HTML during SSR.
This recipe:
