+
+The extension has no effect on web-service lookups.
+
+## Database Reader ##
+
+### Usage ###
+
+To use this API, you must create a new `\GeoIp2\Database\Reader` object with
+the path to the database file as the first argument to the constructor. You
+may then call the method corresponding to the database you are using.
+
+If the lookup succeeds, the method call will return a model class for the
+record in the database. This model in turn contains multiple container
+classes for the different parts of the data such as the city in which the
+IP address is located.
+
+If the record is not found, a `\GeoIp2\Exception\AddressNotFoundException`
+is returned. If the database is invalid or corrupt, a
+`\MaxMind\Db\InvalidDatabaseException` will be thrown.
+
+See the API documentation for more details.
+
+### Example ###
+
+```php
+<?php
+require_once 'vendor/autoload.php';
+use GeoIp2\Database\Reader;
+
+// This creates the Reader object, which should be reused across
+// lookups.
+$reader = new Reader('/usr/local/share/GeoIP/GeoIP2-City.mmdb');
+
+// Replace "city" with the appropriate method for your database, e.g.,
+// "country".
+$record = $reader->city('128.101.101.101');
+
+print($record->country->isoCode . "\n"); // 'US'
+print($record->country->name . "\n"); // 'United States'

-## Exceptions ##
-
-For details on the possible errors returned by the web service itself, see
-the
-[GeoIP2 web service docs](http://dev.maxmind.com/geoip2/geoip/web-service).
-
-If the web service returns an explicit error document, this is thrown as a
-```\GeoIP2\Exception\WebServiceException```. If some other sort of transport
-error occurs, this is thrown as a ```\GeoIP2\Exception\HttpException```.
-The difference is that the web service error includes an error message and
-error code delivered by the web service. The latter is thrown when some sort
-of unanticipated error occurs, such as the web service returning a 500 or an
-invalid error document.
-
-If the web service returns any status code besides 200, 4xx, or 5xx, this also
-becomes a ```\GeoIP2\Exception\HttpException```.
-
-Finally, if the web service returns a 200 but the body is invalid, the client
-throws a ```\GeoIP2\Exception\GeoIP2Exception```.
