+## Run WeTTY as a service daemon
+
+WeTTY can be run as a daemon on your service init confs and systemd services are
+bundled with the npm package to make this easier.
+
+### init.d
+
+```bash
+$ npm -g i wetty
+$ sudo cp ~/.node_modules/wetty/conf/wetty.conf /etc/init
+$ sudo start wetty
+```
+
+### systemd
+
+```bash
+$ yarn global add wetty
+$ cp ~/.node_modules/wetty/conf/wetty.service  ~/.config/systemd/user/
+$ systemctl --user enable wetty
+$ systemctl --user start wetty
+```
+
+This will start WeTTY on port 3000. If you want to change the port or redirect
+stdout/stderr you should change the last line in `wetty.conf` file, something
+like this:
+
+```systemd
+exec sudo -u root wetty -p 80 >> /var/log/wetty.log 2>&1
+```
+
+Systemd requires an absolute path for a unit's WorkingDirectory, consequently
+`$HOME` will need updating to an absolute path in the `wetty.service` file.
