Need help using -d, --destination path and name formatting.

[pawfmrpimt]

So each websites has its own download template when using -d function to tell where to put downloaded files to something like /path/websitename/artists etc,/artwork name/ artwork.something and also formatting the name of the files, so if I were to create my own template of the supported websites how would it look like as a command. Here is some example from yt-dlp:/%(extractor)s/%(artist,uploader,channel)s [%(id)s].%(ext)s I am confusing to what kind of syntax to use in gallery-dl.
