+    1.  This is the base URL of the Nextcloud server that data will be copied to.  For example `https://cloud.bunny-lab.io`
+    2.  You need to create a share on Nextcloud, and configure it as a `File Drop`, then put a password to protect it.  Put that password here.
+    3.  This directory target is the primary focus of the upload / backup / exfiltration.  The script will iterate through this target.  The target can be a directory or a single file. e.g. (`C:\Users\Example`)
+    4.  The tail-end of a nextcloud share link, e.g. `https://cloud.bunny-lab.io/s/<<ABCDEFGHIJK>>`
+    5.  This file is how the script has "persistence".  In case the computer is shut down, rebooted, etc, when it comes back online and the script is re-ran against it, it reads this file to pick up where it last was, and attempts to resume from that point.  If this transfer is meant to be hidden, put this file somewhere someone is not likely to find it easily.
