klugier@X470Pro:Dokumenty/upp $ ./install 
Following command should be used to install required packages:

sudo pacman -Sy --needed gcc make zlib bzip2 gtk3 libnotify openssl clang pkgconfig gdb

Install script can run this command for you, but that will require
your sudo password.
Do you want the script to do that (Y/n)?n // <- You could run it if you want (I skiped, because I have all dependencies)
Please make sure that build dependecies are satisfied.
Continue (Y/n)?

Use prebuilt binary umks32 to accelerate the build (Y/n)?Y
