git clone this repo https://github.com/DirtyUnicorns/DU-Scripts.git
Open up a terminal in a directory where you want to download it and copy/paste this
git clone git@github.com:DirtyUnicorns/DU-Scripts.git
Now with your file browser go into the DU-Scripts folder and copy the build_DU.sh file and paste it in your DU root source.
After doing that, you are ready to use the script simply by this way :
Open up a terminal or if you have the old terminal still open, in your DU root source and type this . build_DU.sh
After, simply respond to what is displayed to compile the build.
In the root of your DU source, type bash nathan-build-script.sh --help
to learn about the script.
