+		Usage Note:
+		-----------
+		Do not use both ajaxSubmit and ajaxForm on the same form.  These
+		functions are mutually exclusive.  Use ajaxSubmit if you want
+		to bind your own submit handler to the form.  For example,
+
+		$(document).ready(function() {
+			$('#myForm').on('submit', function(e) {
+				e.preventDefault(); // <-- important
+				$(this).ajaxSubmit({
+					target: '#output'
+				});
+			});
+		});
+
+		Use ajaxForm when you want the plugin to manage all the event binding
+		for you.  For example,
+
+		$(document).ready(function() {
+			$('#myForm').ajaxForm({
+				target: '#output'
+			});
+		});
+
+		You can also use ajaxForm with delegation (requires jQuery v1.7+), so the
+		form does not have to exist when you invoke ajaxForm:
+
+		$('#myForm').ajaxForm({
+			delegation: true,
+			target: '#output'
+		});
+
+		When using ajaxForm, the ajaxSubmit function will be invoked for you
+		at the appropriate time.
