Voltageshift not working

I was looking a way to undervolt my hackintosh, but when i enter the command line in terminal i get this message: https://imgur.com/JHgNChv

As you guys can see, ive made the directory. But when i run ./voltageshift info it says that there is no directory.

What am i doing wrong here?

I ran sudo chown -R root:wheel (dragging Voltageshift.kext in terminal) and pressing enter. No errors or anything.

System: Dell Latitude E7440 OC 0.7.0 on Big sur 11.5.2

i5-4310u / 12gb ddr3 / intel ac7260 /

Soltuion: Make a shortcut for opening terminal inside a folder. Open the terminal inside the voltageshift_1.25 folder and run sudo chown -R root:wheel VoltageShift.kext

Then ./voltageshift info should work
