+
+The `nsw_fuel_station` sensor platform uses the [NSW Fuel Check App](https://www.fuelcheck.nsw.gov.au/app) data as a source for current fuel price data.
+
+## {% linkable_title Setup %}
+
+To get the station ID for any NSW fuel station you will need to:
+
+- Visit the [Fuel Check App](https://www.fuelcheck.nsw.gov.au/app).
+- Open the developer console of your browser (for Chrome, click View -> Developer -> Developer Tools). Click the "Network" tab in the developer console.
+- In the Fuel Check App, search for your postcode or click "Fuel Near Me".
+- In the developer console, you should see a request to `/FuelCheckApp/v1/fuel/prices/bylocation`. Open this request and preview the response. Find the station you wish to add, and copy down the `ServiceStationID` field.  
+
+## {% linkable_title Configuration %}
