 ### Hash a password
 
-```php
-use ModDev\Password\Scrypt;
+:::php
 
-$scrypt = new Scrypt();
-$securePass = $scrypt->create('user password');
-```
+    use ModDev\Password\Scrypt;
+    
+    $scrypt = new Scrypt();
+    $securePass = $scrypt->create('user password');
 
 ### Check the hashed password against an user input
 
-```php
-use ModDev\Password\Scrypt;
-
-$scrypt = new Scrypt();
-$securePass = 'the stored scrypt value';
-$password = 'the password to check';
-
-if ($scrypt->verify($password, $securePass)) {
-    echo "The password is correct! \n";
-} else {
-    echo "The password is NOT correct.\n";
-}
-
-```
+:::php
+
+    use ModDev\Password\Scrypt;
+    
+    $scrypt = new Scrypt();
+    $securePass = 'the stored scrypt value';
+    $password = 'the password to check';
+    
+    if ($scrypt->verify($password, $securePass)) {
+        echo "The password is correct! \n";
+    } else {
+        echo "The password is NOT correct.\n";
+    }
 
 ### Optional Parameters
 
-```php
-use ModDev\Password\Scrypt;
-
-$scrypt = new Scrypt(array(
-    'cpuDifficulty'      => 16384, //The CPU difficulty. Also called "N" in scrypt documentation. Must be a power of 2.
-    'memoryDifficulty'   => 8, //The memory difficulty. Also called "r" in scrypt documentation.
-    'parallelDifficulty' => 1, //The parallel difficulty. Also called "p" in scrypt documentation.
-    'keyLength'          => 32, //The key length. Must be greater or equal to 16.
-));
-```
+:::php
+    
+    use ModDev\Password\Scrypt;
+    
+    $scrypt = new Scrypt(array(
+        'cpuDifficulty'      => 16384, //The CPU difficulty. Also called "N" in scrypt documentation. Must be a power of 2.
+        'memoryDifficulty'   => 8, //The memory difficulty. Also called "r" in scrypt documentation.
+        'parallelDifficulty' => 1, //The parallel difficulty. Also called "p" in scrypt documentation.
+        'keyLength'          => 32, //The key length. Must be greater or equal to 16.
+    ));
 
 ### Return the hash algorithm
 
-```php
-use ModDev\Password\Scrypt;
+:::php
+    
+    use ModDev\Password\Scrypt;
+    
+    $scrypt = new Scrypt();
+    $passwordhashType = $scrypt->getHashType($hashedPassword);
 
-$scrypt = new Scrypt();
-$passwordhashType = $scrypt->getHashType($hashedPassword);
-```
+### Check if the password needs rehashing
+
+:::php
+
+    use ModDev\Password\Scrypt;
+    
+    $scrypt = new Scrypt();
+    echo $scrypt->needsRehash($hashedPassword);
