In order to add footer information, select User → Edit Configurations in the upper right corner of the dashboard. Once you are on Configurations, click Add then select footer_text_field_one for the key and then type the text that you would like to appear for the value and click the save button under edit. There are five text fields available (footer_text_field_one through footer_text_field_five) therefore you can have up to five lines of footer text.
