How to revert changes?

[SuperMechaDeathChrist]

I installed psx-pi-smbshare with this commands:

cd ~
wget -O setup.sh https://raw.githubusercontent.com/toolboc/psx-pi-smbshare/master/setup.sh
chmod 755 setup.sh
sudo ./setup.sh

... on a raspberry pi 4 running Twister OS (practically Raspberry OS with preinstalled stuff). I'm an amateur with linux operating systems, but I'm not sure how I should go about reverting the changes psx-pi-smshare made without carefully revising what setup.sh does. Is there no easy way to revert back or to uninstall psx-pi-smshare from my system? I couldn't find anything so far. It would be useful if I encounter a problem later on, or if there are conflicts with something else on my system.
