You can simply install invenio-maDMP by running:
$ pip install git+https://github.com/SotosTsepe/invenio-madmpNote
You will also need to replace manually (for now) the json and elasticsearch schemas which come with Invenio, as well as the marshmallow json.py file.
Last but not least you will have to overwrite the record.html file in order to be able to attach files and export their metadata.
