 ## Usage
 
 ```php
-use Ezzatron\LCS\LCSSolver;
+use Eloquent\Lcs\LcsSolver;
 
-$solver = new LCSSolver;
+$solver = new LcsSolver;
 
-$left = array(
-    'B',
-    'A',
-    'N',
-    'A',
-    'N',
-    'A',
-);
-$right = array(
-    'A',
-    'T',
-    'A',
-    'N',
-    'A',
-);
-$expectedLCS = array(
-    'A',
-    'A',
-    'N',
-    'A',
-);
+$sequenceA = array('B', 'A', 'N', 'A', 'N', 'A');
+$sequenceB = array('A', 'T', 'A', 'N', 'A');
 
-$LCS = $solver->longestCommonSubsequence(
-    $left,
-    $right
-);
+// calculates the LCS to be array('A', 'A', 'N', 'A')
+$lcs = $solver->longestCommonSubsequence($sequenceA, $sequenceB);
+```
+
+Elements in sequences can be anything. By default, sequence members are compared
+using the `===` operator. To customize this comparison, simply construct the
+solver with a custom comparator, like so:
 
-if ($LCS === $expectedLCS) {
-    echo 'LCS solver is working.';
-} else {
-    echo 'LCS solver is not working.';
-}
-// the above outputs 'LCS solver is working.'
+```php
+use Eloquent\Lcs\LcsSolver;
+
+$solver = new LcsSolver(
+    function ($left, $right) {
+        // return true if $left and $right are equal
+    }
+);
 ```
