-+ After getting you API key, you have to get your City ID.
-+ Put your API key and City ID in the `Weather Settings`.
++ After this you can choose two locator modes - `Geolocation` and `City`.
++ In City Mode, you have to get your City ID in OpenWeatherMap website.
++ While `Geolocation` mode offers GPS tracking. You don't need to get an ID. Note that you must allow the location permission request.
++ Put your API key in the `Weather Settings`.
++ It's recommended to still put your City ID if you plan to use the `geolocation` mode.
 + Apply.
 
+**Note:**

++ If you're using firefox and you're planning to use the `geolocation`, make sure to set the value of `geo.provider.network.url` to `https://location.services.mozilla.com/v1/geolocate?key=test` in `about:config`. **Google changed its policies, so now it requires a valid API key when accessing their geolocation service.
