+Downloading metadata
+===================
+
+It is possible to download metadata attached to a collection or data object as an interoperable JSON file and use outside of Tier-1 Data. 
+To download metadata go to the tab 'Metadata' and click on the 'Download metadata' button on the right. 
+This will prompt a pop-up box showing the contents of the JSON file to download.
+You can adjust the document by filtering based on schema metadata (Schemas), manual metadata (Other metadata) or automatically extracted metadata (Automatic extraction). 
+Once you are satisfied with your selection you can click 'Download' to download the metadata as a JSON document. 
+To learn more about how the JSON is created you can have a look at the `documentation of our Python module <https://github.com/kuleuven/mango-mdconverter#mango-specific-conversion>`_.
