HOW TO INSTALL A FILE FROM THE AUR ARCH LINUX REPOSITORY
To install arch applications, games and other packages from the Linux repository, you can find everything you need at Arch Linux User Repository. Once you are there you can search for anything using the search text box in the upper right that says Package Search.
For example, to search for Libre Office Suite, just type in Libre Office Suite inside the textbox and hit the return key. You should see a page like this below.
The link you want to click on is the bin file which stands for a binary file, libreoffice-dev-bin. Once you click that link you will then see the package details page where you can then copy a link that looks like a website address. This will be used later to paste into a command to download the files to your GIT directory.
