+    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.
