 help_text="Usage: generate-unique-machine-values.sh
 
-Example:
-    ./generate-unique-machine-values.sh --count 1 --model="iMacPro1,1"
-
 General options:
     --count, -n, -c <count>         Number of serials to generate
-    --model, -m <model>             Device model, e.g. "iMacPro1,1"
+    --model, -m <model>             Device model, e.g. 'iMacPro1,1'
     --csv <filename>                Optionally change the CSV output filename.
+    --tsv <filename>                Optionally change the TSV output filename.
     --output-dir <directory>        Optionally change the script output location.
 
     --help, -h, help                Display this help and exit
     --plists                        Create corresponding config.plists for each serial set.
     --qcows                         [SLOW] Create corresponding boot disk images for each serial set.
 
+Example:
+    ./generate-unique-machine-values.sh --count 1 --model='iMacPro1,1' --plists --qcows
+
+        The above example will generate a
+            - serial
+            - board serial
+            - uuid
+            - MAC address
+            - ROM value based on lowercase MAC address
+            - Boot disk qcow image.
+            - config.plist
+
 Notes:
-    - Default is 1 serial for "iMacPro1,1" in the current working directory.
+    - Default is 1 serial for 'iMacPro1,1' in the current working directory.
+    - Default output is CSV, whereas setting the TSV option will output as tab-separated.
     - CSV is double quoted.
     - If you do not set a CSV filename, the output will be sent to the output-dir.
     - If you do not set an output-dir, the current directory will be the output directory.
-    - Sourcable environment variable shell files will be written to a folder, "envs".
-    - config.plist files will be written to a folder, "plists".
+    - Sourcable environment variable shell files will be written to a folder, 'envs'.
+    - config.plist files will be written to a folder, 'plists'.
