+### Settings
+
+#### Per workflow settings
+Anyone who can create new workflows (admin or regular user) can configure settings for the OCR processing for a specific workflow. These settings are only applied to the specific workflow and do not affect other workflows.
+
+<p align="center">
+  <img width="75%" src="doc/img/per_workflow_settings.png" alt="Per workflow settings">
+</p>
+
+Currently the following settings are available per workflow:
+
+Name | Description
+--- | ---
+Languages | The languages to be used for OCR processing. The languages can be choosen from a dropdown list. For PDF files this setting corresponds to the `-l` parameter of `ocrmypdf`. **Please note** that you'll have to install the appropriate languages like described in the [`ocrmypdf` documentation](https://ocrmypdf.readthedocs.io/en/latest/languages.html).
+Remove background | If the switch is set, the OCR processor will try to remove the background of the document before processing and instead set a white background. For PDF files this setting corresponds to the [`--remove-background`](https://ocrmypdf.readthedocs.io/en/latest/cookbook.html?highlight=remove-background#image-processing) parameter of `ocrmypdf`. **Please note** that without setting this option, the [`--redo-ocr`](https://ocrmypdf.readthedocs.io/en/latest/errors.html?highlight=redo-ocr#page-already-has-text) option will be set, which is **not** compatible to the mentioned `--remove-background`-parameter. So if you set this switch to "on", make sure your PDF documents do not already contain text, otherwise you might find errors in your NC logs and OCR is not possible.
+
+#### Global settings
+As a Nextcloud administrator you're able to configure global settings which apply to all configured OCR-workflows on the current system.
+Go to `Settings` &#8594; `Flow` and scroll down to `Workflow OCR`:

+Processor cores | Defines the number of processor cores to use for OCR processing. When the input is a PDF file, this corresponds to the [`ocrmypdf` CPU limit](https://ocrmypdf.readthedocs.io/en/latest/pdfsecurity.html?highlight=%22-j%22#limiting-cpu-usage). This setting can be especially useful if you have a small backend system which has only limited power.
