Since this is an example for users to follow, i'd word it a bit differently and more verbosely(?). maybe Fields marked with an asterisk <span aria-hidden="true">(*)</span> are required.

Thanks, I fixed this.

small thing but you've changed the title but didn't change the filename (and in turn the slug of the doc). would be more consistent that way, other than that everything is fine
