To simplify installation and maintenance of a filtron instance you can use the
script :origin:`utils/filtron.sh`.  In most cases you will install filtron_
simply by running the command:

.. code::  bash

   sudo -H ./utils/filtron.sh install all

The script adds a ``${SERVICE_USER}`` (default:``filtron``) and installs filtron_
into this user account:

#. Create a separated user account (``filtron``).
#. Download and install Go_ binary in user's $HOME (``~filtron``).
#. Install filtron with the package management from Go_ (``go get -v -u
   github.com/asciimoo/filtron``)
#. Setup a proper rule configuration :origin:`[ref]
   <utils/templates/etc/filtron/rules.json>` (``/etc/filtron/rules.json``).
#. Setup a systemd service unit :origin:`[ref]
   <utils/templates/lib/systemd/system/filtron.service>`
   (``/lib/systemd/system/filtron.service``).
