Most Docusaurus sites are not localized, and this is not really related to self-hosting but applies for CDNs like Vercel/Netlify as well.
For that reason I think it's preferable to move it to a i18n page instead.
For example: https://docusaurus.io/docs/next/i18n/tutorial
I would append a ## Translate your 404 page heading/section

| To serve the correct localized 404 page, you need to configure your server to redirect missing pages to the appropriate locale-specific 404 file. For example: | ||
|
|
||
| - If a visitor requests `/fr/nonexistent-page`, the server should serve `/fr/404.html` instead of `/404.html`. |

Pre-flight checklist
Motivation
This adds documentation for serving localized 404 pages, as discussed in issue #10473. Users with multi-language sites often don't realize their server needs special configuration to serve locale-specific 404 pages like /fr/404.html.
Test Plan
Ran the Docusaurus website locally with
pnpm startand verified the new section appears correctly under "Self-Hosting" at http://localhost:3000/docs/deployment#localized-404-pagesTest links
Deploy preview: https://deploy-preview-_____--docusaurus-2.netlify.app/
