 ## Workflow
-The device takes a photo of your meter at a defined interval. It then extracts the Regions of Interest (ROI's) out of it and runs them through an artificial inteligence. As a result, you get the digitalized value of your meter.

+The SD card can be setup automatically after the firmware got installed. See the [documentation](https://jomjol.github.io/AI-on-the-edge-device-docs/Installation/#remote-setup-using-the-built-in-access-point) for details.

+# Parameter Documentation
+Each parameter which is listed in the [configfile](https://github.com/jomjol/AI-on-the-edge-device/blob/rolling/sd-card/config/config.ini) has its own description page in the folder `parameter-pages` (grouped by the config sections).
+Those pages can be edited as needed.
+
+During a Github action build, those parameter pages will be used to generate the tooltips in the web interface. And they also are used to build the [Online Documentation](https://jomjol.github.io/AI-on-the-edge-device-docs/Parameters).
+
+If you create or rename a parameter, make sure to also update its description page!
+
+## Template Generator
+The script `generate-template-param-doc-pages.py` should be run whenever a new parameter gets added to the config file.
+It then checks if there is already a page for each of the parameters.
+ - If no page exists yet, a templated page gets generated.
+ - Existing pages do not get modified.
+
+If the parameter is listed in `expert-params.txt`, an **Expert warning** will be shown.
+
+If the parameter is listed in `hidden-in-ui.txt`, a **Note**  will be shown.

+!!! Note
+    This parameter is not accessible through the Web Interface Configuration Page!
+
+The GPIO Interface is prepared to report it's status and status changes as a MQTT topic. With this parameter you configure the MQTT main topic, under which the status is published.
+As this parameter is still experimental it can only be set manually in the `config.ini` itself and has not been tested in detail so far.
