You need Ansible installed on your system.
For example, to install the Algorand node on your local machine issue the following (after changing algonaut to your username:
ansible-playbook --connection=local --inventory 127.0.0.1, --limit 127.0.0.1 -e admin_user=algonaut -e admin_user_group=algonaut -i example_hosts node_playbook.yml --ask-become-pass
For now, only Debian based distributions and CentOS 7 use package manager for installation, the other OSes use the updater script or binary installation (MS Windows). Nevertheless, 2.8 version of the Algorand node will allow the package manager installation for all the RPM based distros and the repo will be updated afterwards.
Feel free to ask any question!
