+## Default Configuration
+
+Below is the default config file for the restserver and joex. If you
+create a config file, you only need to include settings that differ
+from the default config.
+
+## Rest Server
+
+{{ incl_conf(path="templates/shortcodes/server.conf") }}
+
+
+## Joex
+
+{{ incl_conf(path="templates/shortcodes/joex.conf") }}
+
+
+## Environment Variables
+
+Environment variables can be used when there is no config file
+supplied.
+
+There is one caveat: The configuration files above reuse values by
+referencing them. This applies for example to the `app-id` - it is
+used at other places, where the config file simply references it via
+its full path. For example for the scheduler name, the default value
+is `${docspell.joex.app-id}`. This way the value of `scheduler.name`
+is always the same as `app-id`. But this doesn't work with env
+variables! Here you'd need to update each such value.
+
+For example, when creating multiple joex', they must have different
+`app-id`s and with this, these values need to be set as well:
+
+```
+DOCSPELL_JOEX_APP__ID=joex2
+DOCSPELL_JOEX_PERIODIC__SCHEDULER_NAME=joex2
+DOCSPELL_JOEX_SCHEDULER_NAME=joex2
+```
+
+The listing below shows all possible variables and their default
+values.
+
+{{ incl_conf(path="templates/shortcodes/config.env.txt") }}
