+## `kt-error-url`
+
+The `kt-error-url` attribute allows you to send client-side errors to a specified URL. It is typically put on the
+body tag, so all errors are caught and send to the server.
+
+```html
+\
+
+
+```
+When a client side error is caught by kutty it will be `POST`-ed to the given URL, with the following JSON format:
+
+```json
+ { "elt": elt.id, "event": eventName, "detail" : detail }
+```

+## `kt-history-elt`
+
+The `kt-history-elt` attribute allows you to specify an element as the place
+where [history support](/docs#history) will capture HTML from and restore it to
+during history navigation.
+
+By default the `body` tag is used but you may want to narrow this to a child
+element. Be careful if you do, however: the element must be present on all pages
+in your application or a history navigation may fail.
+
+Here is an example:
+
+```html
+
+
+
+ ...
+
+
+```
+
+Kutty will snapshot and restore history to the inner `.content` div.
+
+### Notes
+
+* By and large we recommend not using this attribute
