This is the default 404 error page file distributed with the nginx web server on Fedora systems. It is intended for website administrators and server operators who need to manage the user experience when a requested page cannot be found. The file serves as a starting point, providing a basic HTML structure that informs a visitor the page is not found, which you should modify to match your site's design and provide useful navigation.

• Default Error Page: This is the standard HTML file (/usr/share/nginx/html/404.html) served when nginx encounters a 404 error, indicating a missing resource.
• Administrator Guidance: The page includes comments directing the site administrator to customize the content for their specific website.
• Configuration Reference: It notes the related error_page directive within the main nginx configuration file (/etc/nginx/nginx.conf), which controls how error responses are handled.
• Basic HTML Structure: The file provides a simple, valid HTML template that displays a clear error message, which can be edited using any text editor.
• Fedora Distribution: This specific version of the error page is bundled with nginx packages in the Fedora Linux distribution, serving as a local fallback.
