+    sudo apt install ./task_linux_amd64.deb && rm task_linux_amd64.deb
+    ```
+
+## Nutzung
+
+* Alle Datenquellen harvesten und transformieren (parallelisiert)
+
+  ```
+  task default
+  ```
+
+* Eine Datenquelle harvesten und transformieren
+
+  ```
+  task siegen:default
+  ```
+
+* Cache einer Datenquelle löschen
+
+  ```
+  task siegen:delete
+  ```
+
+* Verfügbare Tasks auflisten
+
+  ```
+  task --list
+  ```
+
+## Konfiguration
+
+* Umgebungsvariablen in [Taskfile.yml](Taskfile.yml)
+* Workflow für die Datenquellen in [tasks](tasks)
+  * Beispiel: [tasks/siegen.yml](tasks/siegen.yml)
+* Transformationsregeln in [rules](rules)
+  * Beispiel: [rules/siegen/hbz.json](rules/siegen/hbz.json)
+
+## OAI-PMH Data Provider
+
+Für die Bereitstellung der transformierten Daten wird der dateibasierte OAI-PMH Data Provider [oai_pmh](https://github.com/opencultureconsulting/oai_pmh) genutzt. Installations- und Nutzungshinweise sind dort zu finden.
