Documenting commands # or $ before sudo?

This might be a stupid question, but hear me out.
I regularly document steps to install various software for myself on my wiki
More recently, I managed to use different custom text in the source markdown to prepend # and $ automatically, so commands can be copied more easily while still clarifying if it should be run as a normal user or as root.

Run command as user

 undefined

    
$ some cool command

  

Run command as root/superuser with sudo

 undefined

    
# some dangerous command

  

I usually remove and sudo and use the # prefix. However, in some cases, the sudo actually does something different that needs to be highlighted. For example, I might use it to execute a command as the user www-data

 undefined

    
sudo -u www-data cp /var/www/html/html1 /var/www/html/html2


  

I often use $ as a prefix, but # would also make sense.
How would you prefix that line?
