LMS on Raspberri PI

Hi All
I have just managed to setup my old SB classic again with the LMS on a laptop. All is working well incl. Spotify.
During my LMS setup searches I have read here and there a bit regarding setting up a LMS on Raspberry. For a long time I have been thinking to get a Raspberry Pi for Pi-Hole.
Now would be the time for me to get both setup. Would someone be able to elaborate a bit how to go about it as I am thinking about a RB pi 4b??

Thanks in advance
