+## Auxiliary files:   
+Sycamore requires users to manually download files from the Beiwe website to create some outputs. These files can be downloaded by clicking "Edit this Study" on the study page, and clicking on the relevant file. When running Sycamore, pass the path to the file downloaded by clicking "Export study settings JSON file" under "Export/Import study settings" to the `config_path` argument. Pass the file downloaded by clicking "Download Interventions" next to "Intervention Data" to the `interventions_filepath` argument. And, pass the file downloaded by clicking "Download Surveys" next to "Survey History" to the `history_path` argument.
