Ah ok that was what I was going to do but will I need to do anything else for it? not that doing anything else is an issue for me

git clone https://gitlab.manjaro.org/manjaro-arm/applications/manjaro-arm-installer
cd manjaro-arm-installer
sudo bash manjaro-arm-installer arm-unstable

By the way is it wise to use unstable or is that necessary at the moment?
