+Instaloader as Cronjob
+^^^^^^^^^^^^^^^^^^^^^^
+
+Instaloader is suitable for running as a cronjob to periodically update your
+personal Instagram archive. The :option:`--quiet` option disables user
+interactions and logging of non-error messages. To non-interactively use
+Instaloader logged-in, create a session file, e.g. in your home directory::
+
+   instaloader --login=your_username --sessionfile=~/.instaloader-session
+
+Then use the same parameters in your cronjob to load the session and download
+the given targets::
+
+   instaloader --login=your_username --sessionfile=~/.instaloader-session --quiet <target> [...]
+
+Without :option:`--sessionfile` option, Instaloader saves the session file in
+a path within your temporary directory.
+
+Programming Instaloader
+^^^^^^^^^^^^^^^^^^^^^^^
+
+If your task cannot be done with the command line interface of Instaloader,
+consider taking a look at the :ref:`python-module-instaloader`.
+Instaloader exposes its internally used methods and structures, making it a
+powerful and intuitive Python API for Instagram, allowing to further customize
+obtaining media and metadata.
