+### GET Parameter Manipulation
+Some users may require GET parameters to be part of their POST. Any parameters you pass onto the Apprise command line are interpreted by Apprise itself as options/actions you wish to perform (such as changing `method=update`, or `cto=3`). To have Apprise ignore what was specified and past the content `as-is` upstream, you just need to prefix your entries with a minus (`-`) symbol.
+```bash
+# The below for example would post to http://localhost:8000?token=abcdefg
+#
+# The `-` symbol will get stripped off when the upstream post takes place
+# Apprise knows not to do anything with the argument at all and pass it along as is.
+apprise -vv -t "Test Message Title" -b "Test Message Body" \
+   "form://localhost:8080/?-token=abcdefg"
+
+# If you want to pass more then one element, just chain them:
+# The below would send a a POST to:
+#  https://example.ca/my/path?key1=value1&key2=value2
+#
