 ### Configuration
-wip..
+Config file are located at `config/abstract-ip-geolocation.php` after publishing provider element.
+
+#### Fields
+By default, all fields are returned by the Abstract API, but you can choose to retrieve just the values you're interested in from the API.
+To do this, you need to specify the fields you want (the list of fields is available here https://docs.abstractapi.com/ip-geolocation#request-parameters).
+
+```php
+/*
+|--------------------------------------------------------------------------
+| Geolocation Fields
+|--------------------------------------------------------------------------
+| You can include a fields value in the query parameters with a comma
+| separated list of the top-level keys you want to be returned. For example
+| "fields => 'city,region'" will return only the city and region in the response.
+|
+| see: https://docs.abstractapi.com/ip-geolocation#request-parameters
+*/
+
+'fields' => null,
+```
+
+Once you've specified the fields you want (e.g. `country,currency`) only these values will be returned by the API and in your geolocations DTO object,
+you'll only have the `country` and `currency` values available - the others will be null.
+
+To access this information, consult `session()`.
+
+```php
+$geolocation = session()->get('abstract-ip-geolocation');
+
+$geolocation->country // return "France"
+$currency = $geolocation->currency // instance of \Laravelcm\AbstractIpGeolocation\DataObject\Currency
+```
+
+#### DTO
+The available DTO classes are listed below. In the json return from the Abstract Geolocation API, all objects are represented by DTO classes
 
-### Test
-wip..
+- `\Laravelcm\AbstractIpGeolocation\DataObject\GeolocationData` which represents the geolocation class containing all information relating to the user via its IP address
+- `\Laravelcm\AbstractIpGeolocation\DataObject\Connection` which represents the DTO class for its connection origin information
+- `\Laravelcm\AbstractIpGeolocation\DataObject\Currency` which represents the DTO class for the currency
+- `\Laravelcm\AbstractIpGeolocation\DataObject\Flag` which represents the DTO class for country flag information
+- `\Laravelcm\AbstractIpGeolocation\DataObject\Timezone` which represents the DTO class for Timezone information
+- `\Laravelcm\AbstractIpGeolocation\DataObject\Security` which represents the DTO class for security information, lets you know whether the user is using a VPN or not
