 The integration is able to work with Kiosk mode, or with a Northbound API / OpenAPI account, see below for more details.
 
 ## Installation
 
-This integration is part of the default HACS repositories, so can add it directly from HACS or add this repository as a custom repository in HACS.

 Yes. There is a [Postman] Collection available. You can import it in Postman and start working with it.

+The collection is available

 You will need to create an environment in Postman with the following variables:
 
 * `USERNAME`, your Northbound API / OpenAPI username
 * `SYSTEMCODE`, your Northbound API / OpenAPI password
 * `URL`, the url you will query

+### I need to change the Kiosk URL
+
+The Kiosk URL is valid for 1 year. After that you will need to update the URL. At this point there is no way to update
+the URL without re-adding the integration. This can result in data los.
+
+You can work around this, **but this is not recommended and is at your own risk**:
+
+Open the file `.storage/core.config_entries` in the Home Assistant directory.
+
+There will be an entry like below"
+
+```json
+  {
+  "entry_id": "8cd2320a2969e84XXX",
+  "version": 1,
+  "domain": "fusion_solar",
+  "title": "Fusion Solar",
+  "data": {
+    "kiosks": [
+      {
+        "name": "Foo",

+      }
+    ],
+    "credentials": {}
+  },
+  ...
+}
+```
+
+Update the `url`. And restart Home Assistant.
+
+### How can I verify my Northbound API / OpenAPI credentials?
+
+You can verify your credentials by doing a `curl` call.
+
+```
+curl --location 'https://eu5.fusionsolar.huawei.com/thirdData/login' \
+--header 'Content-Type: application/json' \
+--data '{
+    "userName": "XXX",
+    "systemCode": "YYY"
+}'
+
+```
+
+Check if you need to alter the base hostname https://eu5.fusionsolar.huawei.com. And replace XXX with your username and
+YYY with your password.
+
+The response should look like:
+
+```json
+{
+  "data": null,
+  "success": true,
+  "failCode": 0,
+  "params": {},
+  "message": null
+}
