 You can use alsa instead of pulse, but don't unless you're on a Pi.
 
 Since this is run as the mpd user, you'll need to grant that user pulse acceess, often with the user-group `pulse` or `pulse-access`, but your distro may vary.
 
-> sudo usermod -aG pulse-access mpd
+```bash
+sudo usermod -aG pulse-access mpd
+```
 
 Working with mpd will be easier if you have access to its files, so maybe:
 
-> sudo usermod -aG mpd $USER
+```bash
+sudo usermod -aG mpd $USER
