Pihole - is this correct

I started from scratch on my server over the weekend due to too much confusion and problems. So pihole has been freshly installed, but has it been installed into two locations?
Is this correct?

root@HC1:~# ls -al /var/www/pihole/
total 40
drwxr-xr-x 2 root root  4096 Aug  2 15:57 .
drwxr-xr-x 4 root root  4096 Aug  2 15:57 ..
-rw-r--r-- 1 root root 13072 Aug  2 15:57 blockingpage.css
-rw-r--r-- 1 root root 14761 Aug  2 15:57 index.php
root@HC1:~# ls -al /var/www/html/pihole/
total 40
drwxr-xr-x 2 root root  4096 Aug  2 15:57 .
drwxr-xr-x 4 root root  4096 Aug  2 15:57 ..
-rw-r--r-- 1 root root 13072 Aug  2 15:57 blockingpage.css
-rw-r--r-- 1 root root 14761 Aug  2 15:57 index.php

yes that should be correct. Usually /var/www/pihole is a symlinc to /var/www/html/pihole

root@DietPi4:~# ls -la /var/www/ |grep pihole
lrwxrwxrwx  1 root root    11 Jan 18  2020 pihole -> html/pihole
root@DietPi4:~#
