 The only major distribution that currently packages Oragono is Arch Linux; the aforementioned AUR package includes a systemd unit file. However, it should be fairly straightforward to set up a productionized Oragono on any Linux distribution. Here's a quickstart guide for Debian/Ubuntu:
 
 1. Create a dedicated, unprivileged role user who will own the oragono process and all its associated files: `adduser --system --group oragono`. This user now has a home directory at `/home/oragono`.
-1. Copy the executable binary `oragono`, the config file `ircd.yaml`, the database `ircd.db`, and the self-signed TLS certificate (`tls.crt` and `tls.key`) to `/home/oragono`. Ensure that they are all owned by the new oragono role user: `sudo chown oragono:oragono /home/oragono/*`. Ensure that the configuration file logs to stderr.
