Hive OS/Ubuntu How to make package from files (git clone)?

I have a problem with installation of Windscribe VPN manually through Ubuntu system. I found this files from git: https://github.com/hkuchampudi/Windscribe

I cloned it from git in the folder. I downloaded and installed pacman too but I don't have "makepkg" command. How should I created package in Ubuntu with tar extension (or deb extension) and install my files?

Thanks in advance for directing me what should I do. I only have terminal and don't have display version of Ubuntu.
