 If you are already using another way to include your JavaScript, you can depend on the value of the Choice-Cookie.  
 It's named `KD_GDPR_CC` and contains all identifiers of groups and cookies you defined in Backend while configuration. The payload of that cookie could look like this:
 ```json
-{   "consents":[
+{
+   "consents": [
       "necessary",
       "analytics",
       "marketing"
-
-],
-   "consentDate":"Tue, 11 Feb 2020 11:35:23 GMT",
-   "expireDate":"Wed, 10 Feb 2021 23:00:00 GMT"
+   ],
+   "consentDate": "Tue, 11 Feb 2020 11:35:23 GMT",
+   "expireDate": "Wed, 10 Feb 2021 23:00:00 GMT"
 }
 ```

 So just check *consents* and load the needed JavaScript.  
 *Pro-Tip: If you are using Google Tag Manager to add your JS-Tags, you can define a custom variable of type "First-Party-Cookie", which can be used as condition inside triggers then.*

+#### Add a Re-open link
+To create a link for reopening the banner, you only have to place a link with `#GDPR-CC-open-settings` as target: 
+```html
+<a href="#GDPR-CC-open-settings">Cookie-Settings</a>
+``` 
+After clicking on such a link, the cookie-banner will be loaded via API. Old settings are used as presets.
+
+#### Versioning
+In some cases, it may be necessary to show the cookie-banner to people who have actually already accepted it. For example, if a new cookie has been added.  
+To do this, you only need to edit the version date. You can find it in the inspector of the cookie-settings NodeType:   
+![version-date setting](Documentation/Images/version-date.png)  
+
+After the date has been changed, the banner will be shown again to all visitors, who have submitted the cookie banner before this date. Old settings are used as presets.
