Installation Godot (Mono Version) on Manjaro

 Firstly, let's open this page. You will see some details about package:

Open the terminal emulator and type this command. This command will download godot-mono source files:

git clone https://aur.archlinux.org/godot-mono-bin.git

Let's build this source files with this command, but we have to go inside the source folder at first:

cd godot-mono-bin
makepkg -si

There will be downloading and installation processes at this moment. Probably at this process, you have to proceed some questions with Y. That's it.
