1. Extract resources.zip
2. Modify preprocessing.ini
    The most important settings to change are 
        - $RESOURCES_FOLDER: The folder where the contents of resources.zip have been extracted to
        - INPUT_FOLDER: the folder where your input documents are located
        - OUTPUT_FOLDER: the folder where the processed documents should be saved to
    In order to activate/deactivate engines, set them to active=true or active=false

Running the pipeline:
call
    java -jar nlp-pipeline.jar preprocessing.ini
