 If you need help with these options, then you should consult the borg
 documentation or search my blog at
-[https://mytechiethoughts.com](https://mytechiethoughts.com) for borg. This is
-especially true if you want to understand why an SSH key and passphrase are
-preferred and why just a passphrase on it's own presents problems automating
-borg backups.
+[https://mytechiethoughts.com](https://mytechiethoughts.com) for borg.  Here's a
+very brief overview:
+
+#### Line 1: Path to borg base directory
+
+This is primary directory on your local system where your borg configuration is
+located, **NOT* the path to your borg binary.  The base directory contains the
+borg configuration, cache, security files and keys.
+
+#### Line 2: Path to SSH key for remote server
+
+This is the SSH key used to connect to your remote (backup) server where your
+borg repo is located.  **This is NOT your borg repo key!**
+
+> Please note:  If you are planning on executing this script via cron or some
+> other form of automation, it is *highly recommended* that you use an SSH key
+> **without** a password!  SSH is designed such that passwords cannot simply be
+> passed to it via environment variables, etc. so this is something not easily
+> automated by a script such as this for security reasons.  As such, your
+> computer will sit and wait for you to enter the password and will NOT execute
+> the actual backup portion of the script until the SSH key password is provided.
+> 
+> If you really want/need to use an SSH key password, you will have to look into
+> somethign like GNOME keyring or SSH-agent to provide a secure automated way to
+> provide that password to SSH and allow this script to continue.
+>
+> In practice, SSH keys without passwords are still quite safe since the key
+> must still be known in order to connect and most keys are quite long.  In
+> addition, they key only connects to the remote server, your actual information
+> within the borg repository is still encrypted and secured with both a key and
+> password.
+
+#### Line 3: Connection string to remote repo
+
+This is the full server and path required to connect to your borg repo on the
+remote server.  Very often it is the in the form of:
+
+```
+user@servername.tld:repo-name/
+```
+
+for rsync.net it is in the following form:
+
+```
+username@server-number.rsync.net:repo-name/
+```
+
+#### Line 4: Password for borg repo/repo key
+
+This is the password needed to access and decrypt your *borg repo*.  Assuming
+you set up your borg repo using recommended practices, this will actually be the
+password for your *borg repo private key*.  **This is NOT your SSH key
+password!**
