 # Examples section
 
 In this subfolder are some examples how to use the docker images.

+There is currently one section:
 
-* [`dockerfiles`](https://github.com/friendica/docker/tree/stable/.examples/dockerfiles)
 * [`docker-compose`](https://github.com/friendica/docker/tree/stable/.examples/docker-compose)
 
-The `dockerfiles` are derived images that add or alter certain functionalities of the default docker images.
 In the `docker-compose` subfolder are examples for deployment of the application.
 
-## Dockerfiles

-The Dockerfiles use the default images as base image and build on top of it.

-Examples | Descriptions
--------- | -------
-[cron](https://github.com/friendica/docker/tree/stable/.examples/dockerfiles/cron) | uses supervisor to run the cron job inside the container (so no extra container is needed).
-
 ## docker-compose
 
 In `docker-compose` additional services are bundled to create a complex Friendica installation.

-## Using the cron job
+## Background tasks
 
-There are three options to enable the cron-job for Friendica:
+Friendica requires background tasks to fetch and send all kind of messages and maintain the complete instance.
+This setup is crucial for the Friendica node.
+There are two options to enable background tasks for Friendica:
 
--	Using the default Image and activate the cron-job (see [Installation](https://friendi.ca/resources/installation/), sector `Activating scheduled tasks`)
+-	Using the default Image and manually setup background tasks (see Friendica [Install](https://github.com/friendica/friendica/blob/2021.03-rc/doc/Install.md#required-background-tasks))
--	Using the default image (apache, fpm, fpm-alpine) and creating **two** container (one for cron and one for the main app)
+-	Using the default image (apache, fpm, fpm-alpine) and starting a dedicated `cron` instance and use `cron.sh` as startup command (like this [Example](https://github.com/friendica/docker/blob/stable/.examples/docker-compose/insecure/mariadb-cron-redis/apache/docker-compose.yml))
--	Using one of the additional, prepared [`cron dockerfiles`](https://github.com/friendica/docker/tree/stable/.examples/dockerfiles/cron)
 
 ## Possible Environment Variables
 
 **Friendica Settings**
 
--	`FRIENDICA_URL` The Friendica URL.
+-	`FRIENDICA_URL` The Friendica complete URL including protocol, domain and subpath (example: https://friendica.local/sub/ ).
 -	`FRIENDICA_TZ` The default localization of the Friendica server.
 -	`FRIENDICA_LANG` The default language of the Friendica server.
 -	`FRIENDICA_SITENAME` The Sitename of the Friendica server.

 You can preconfigure everything that is asked on the install page on first run.
