-**Deprecation notice: [Gatsby has been abandoned](https://github.com/gatsbyjs/gatsby/issues/38696) so maintaining this plugin does not make much sense. It will only receive occasional dependency updates and will be archived at the end of 2024. If you choose to switch to [Astro](https://astro.build), you can use [astro-redirect-from](https://github.com/kremalicious/astro-redirect-from).**
