In order to start, you need to install Ansible. Installing Ansible via pip requires pulling in a lot of dependencies, including a full compiler suite. It would be easier to use apt, however, Ubuntu 18.04 only comes with Ansible 2.0.0.2. The easiest solution is to install the Ansible PPA for a newer version of Ansible via apt, however, using a PPA requires installing `software-properties-common`.
**Warning**: Algo is intended to be run on a standalone server. If you run Algo on your existing server, the iptables rules will be overwritten. If you don't want to overwrite the rules, you must deploy via `ansible-playbook` and skip the `iptables` tag as described in [deploy-from-ansible.md](deploy-from-ansible.md). Other changes are also made, which can break other services running on your server (web, mail, etc.).
