Sorting site taxonomy

Hi - just wanted to also ask if anyone knows if the 404 in the root of the site should load automatically, or is it a usual requirement to add an .htaccess with this:

ErrorDocument 404 /404.html

When I said it was working above, I had been looking directly at the page, not entering erroneous URL paths.

When I tried http://mysite.com/blahblah, it came up with a default Apache handler, so I went ahead and handled loading this custom page with .htaccess.

I was just wondering what’s the convention, generally, or if Hugo is supposed to do this for us.
