+### ip2region SDK for PHP
 
+### Installation
 > composer require chinayin/ip2region
+
+### Quick Examples
+```php
+use lionsoul2014\Ip2Region;
+
+$ip2region = new Ip2Region;
+
+$ip = '220.181.38.150';
+$data = $ip2region->memorySearch($ip);
+$data = $ip2region->binarySearch($ip);
+$data = $ip2region->btreeSearch($ip);
+
+// binary算法/b-tree算法/Memory算法：
+// 0.x毫秒/0.1x毫秒/0.1x毫秒
+// 任何客户端b-tree都比binary算法快，当然Memory算法固然是最快的！
