 # How to install
 
-`pip3 install ereb`
+Under `root`:
+```
+pip3 install ereb
+```
+
+This will install `ereb` to `/usr/local/bin/ereb`.
+
+## For Debian/Ubuntu users
+
+If you want to properly install ereb so that it starts on system start, make use of systemd.
+
+1. Create a proper init script: `vim /etc/init.d/ereb`:
+ ```
+ #!/bin/bash
+ ### BEGIN INIT INFO
+ # Provides:          ereb
+ # Required-Start:    $remote_fs $syslog
+ # Required-Stop:     $remote_fs $syslog
+ # Default-Start:     2 3 4 5
+ # Default-Stop:      0 1 6
+ # Short-Description: Start ereb at boot time
+ # Description:       Ereb is a cool crontab with web interface.
+ ### END INIT INFO
+
+ PIDFILE=/var/run/ereb.pid
+
+ case $1 in
+    start)
+        # as a detached process
+        /usr/local/bin/ereb >> /var/log/ereb.log 2>&1 &
+        # Get its PID and store it
+        echo $! > ${PIDFILE}
+    ;;
+    stop)
+       kill `cat ${PIDFILE}`
+       # Now that it's killed, don't forget to remove the PID file
+       rm ${PIDFILE}
+    ;;
+    *)
+       echo "usage: ereb {start|stop}" ;;
+ esac
+ exit 0
+ ```
+2. Create a systemd unit: `vim /lib/systemd/system/ereb.service`:
+ ```
+ [Unit]
+ SourcePath=/etc/init.d/ereb
+ Description=Easy installable cron with web interface
+
+ [Service]
+ Type=forking
+ PIDFile=/var/run/ereb.pid
+ Restart=always
+ TimeoutSec=5min
+ IgnoreSIGPIPE=no
+ KillMode=process
+ GuessMainPID=no
+ RemainAfterExit=yes
+ ExecStart=/etc/init.d/ereb start
+ ExecStop=/etc/init.d/ereb stop
+ ```
+3. Place the unit under `multi-user` target:
+ ```
+ ln -s /lib/systemd/system/ereb.service /etc/systemd/system/multi-user.target.wants/ereb.service
+ ```
+4. Enable the service so that it starts on boot:
+ ```
+ systemctl enable ereb.service
+ ```
+
+Now you can try to `reboot` your server and make sure that `ps aux | grep ereb | grep -v grep` shows up running ereb instance.

+And ofcourse, don't forget to
+```
+mkdir /var/run/ereb
+mkdir /var/log/ereb
+```
+*Note: Now you can see `ereb` log in `/var/log/ereb/ereb.log`.*
