-### Usage
+Supports SilverStripe 4
 
-##### `__construct` options
+## Usage
 
-|Option|Default|Description|
-|------|-------|-----------|
-|`field_names`|See `GoogleMapField.yml`'s `default_options.field_names`|A map of field names to save the map data into your object.|
+### Minimal configuration
+
+Given your DataObject uses the field names `Lat` and `Lng` for storing the latitude and longitude respectively then the
+following is a minimal setup to have the map show in the CMS:
+
+```php
+use SilverStripe\ORM\DataObject;
+use BetterBrief\GoogleMapField;
+
+class Store extends DataObject
+{
+    public static $db = array(
+        'Title' => 'Varchar(255)',
+        'Latitude' => 'Varchar',
+        'Longitude' => 'Varchar',
+    );
+    
+    public function getCMSFields() {
+        $fields = parent::getCMSFiels();
+        
+        // add the map field
+        $fields->addFieldToTab('Root.Main', new GoogleMapField(
+            $this,
+            'Location'
+        ));
+        
+        // remove the lat / lng fields from the CMS
+        $fields->removeFieldFromTab('Root.Main', 'Lat');
+        $fields->removeFieldFromTab('Root.Main', 'Lng');
+        
+        return $fields;
+    }
+}
+```
+
+Remember to set your API key in your site's `config.yml`
 
-##### make sure `api_key` config added in site yml file
 ```yml
 BetterBrief\GoogleMapField:
   default_options:
-    api_key: 'GOOGLE_API_KEY'
+    api_key: '[google-api-key]'
+```
+
+## Optional configuration
+
+### Configuration options
+
+You can either set the default options in your yaml file (see [_config/googlemapfield.yml](_config/googlemapfield.yml)
+for a complete list) or at run time on each instance of the `GoogleMapField` object.
+
+#### Setting at run time
+
+To set options at run time pass through an array of options (3rd construct parameter):
+
+```php
+use BetterBrief\GoogleMapField;
+
+$field = new GoogleMapField(
+    $dataObject,
+    'FieldName',
+    array(
+        'api_key' => 'my-api-key',
+        'show_search_box' => false,
+        'map' => array(
+            'zoom' => 10,
+        ),
+        ...
+    )
+);
 ```
 
-##### `Field` options
+#### Customising the map appearance
+
+You can customise the map's appearance by passing through settings into the `map` key of the `$options` (shown above).
+The `map` settings take a literal representation of the [google.maps.MapOptions](https://developers.google.com/maps/documentation/javascript/reference?csw=1#MapOptions)
+
+For example if we wanted to change the map type from a road map to satellite imagery we could do the following:
+
+```php
+use BetterBrief\GoogleMapField;
+
+$field = new GoogleMapField(
+    $object,
+    'Location',
+    array(
+        'map' => array(
+            'mapTypeId' => 'SATELLITE',
+        ),
+    )
+);
+```

+## Google Maps API key

+
+## Geocoding access - enabling the search box
 
-|Option|Default|Description|
-|------|-------|-----------|
-|`coords`|Your object's latitude and longitude|The intial coordinates of the map - note: this is not the default value if no object exists|
-|`map`|Zoom of 14, map type of ROADMAP|A [google.maps.MapOptions](https://developers.google.com/maps/documentation/javascript/reference?csw=1#MapOptions) object|
+To use the search box to find locations on the map, you'll need to have enabled the Geocoding API as well. Please see
+[the official docs](https://developers.google.com/maps/documentation/javascript/geocoding#GetStarted)
