+:::caution
+We recommend not putting your font files in [the `public/` directory](/en/reference/configuration-reference/#publicdir). Since Astro will copy these files into that folder at build time, this will result in duplicated files in your build output. Instead, store them somewhere else in your project, such as in [`src/`](/en/reference/configuration-reference/#srcdir).
