== Procedure

Use the following commands as the `root` user or under the `sudo` utility.

. Install the [package]_dnf-automatic_ package:
+
----
# dnf install dnf-automatic
----

. Edit the [filename]`/etc/dnf/automatic.conf` configuration file as needed. See the http://dnf.readthedocs.io/en/latest/automatic.html[DNF Automatic] documentation for details. 

. Enable and start the `systemd` timer:
+
[literal,subs="+quotes,attributes"]
----
# systemctl enable _timer_
# systemctl start _timer_
----
+
Replace `_timer_` with one of following ones depending on what action you want to do:
+
--
* `dnf-automatic-install.timer` to download and install packages
* `dnf-automatic-download.timer` to only download packages
* `dnf-automatic-notifyonly.timer` to only get a notification using configured emitters in the [filename]`/etc/dnf/automatic.dnf` file.
--
+
For example:
+
----
# systemctl enable dnf-automatic-install.timer
Created symlink /etc/systemd/system/basic.target.wants/dnf-automatic-download.timer → /usr/lib/systemd/system/dnf-automatic-download.timer.
# systemctl start dnf-automatic-install.timer
----

. Ensure that the timer has been successfully enabled and started:
+
[literal,subs="+quotes,attributes"]
----
# systemctl status _timer_
----
+
Replace `_timer_` with the timer from the previous step, for example:
+
----
# systemctl status dnf-automatic-install.timer
● dnf-automatic-download.timer - dnf-automatic-download timer
   Loaded: loaded (/usr/lib/systemd/system/dnf-automatic-download.timer; enabled; vendor preset: disabled)
   Active: active (waiting) since Thu 2017-12-14 11:33:14 CET; 7s ago
