 NB. Once enabled, the collectors are added (and could produce extra overhead), so if you want to use the debugbar in production, disable in the config and only enable when needed.
 
+## Storage
+
+Debugbar remembers previous requests, which you can view using the Browse button on the right. This will only work if you enable `debugbar.storage.open` in the config. 
+Make sure you only do this on local development, because otherwise other people will be able to view previous requests.
+In general, Debugbar should only be used locally or at least restricted by IP.
+It's possible to pass a callback, which will receive the Request object, so you can determine access to the OpenHandler storage.
