Getting started
Install manjaro-tools-iso-git from the repositories.
pamac install manjaro-iso-git
The ISO profiles are not included so we have to clone the profile repositories anywhere in our home directory.
mkdir /home/username/profiles
cd /home/username/profiles
git clone https://gitlab.manjaro.org/profiles-and-settings/iso-profiles.git
After that is done buildiso will automatically pick up were your profiles are.
Lets use XFCE as an examples, desktop packages can be added or removed under:
/home/username/profiles/iso-profiles/manjaro/xfce/Packages-Desktop
Build options can be changed under:
/home/username/profiles/iso-profiles/manjaro/xfce/profile.conf
Operating system configurations can be added or removed under:
/home/username/profiles/iso-profiles/manjaro/xfce/desktop-overlay/etc for your installed system or under:
/home/username/profiles/iso-profiles/manjaro/xfce/live-overlay/etc for your live system.
After you have made changes to your profile run buildiso.
buildiso -p xfce
