Usage

  1. Install git and clone repo:

    • Debian:

      sudo apt install -y git && git clone [email protected]:SimonLammer/dotfiles.git ~/.dotfiles

    • Fedora:

      sudo dnf update -y && sudo dnf install -y make https://mirrors.rpmfusion.org/free/fedora/rpmfusion-free-release-$(rpm -E %fedora).noarch.rpm https://mirrors.rpmfusion.org/nonfree/fedora/rpmfusion-nonfree-release-$(rpm -E %fedora).noarch.rpm

  2. Perform ansible magic:

    make setup

    or

    ansible-galaxy install -r requirements.yml
ansible-playbook setup.yml -e 'ansible_python_interpreter=/usr/bin/python3' -u `whoami`

  3. Remaining setup
