+## Strict vs Loose comparisons
+
+**Comparisons are strict by default**, but you can specify that you want to do a loose comparison passing a boolean as a third parameter for `compare` method, or calling the `looseComparison`
+
+```php
+// This will deactivate the strict comparison mode
+ArrayDiffMultidimensional::compare($new, $old, false);
+
+// This method call is equivalent
+ArrayDiffMultidimensional::looseComparison($new, $old);
+```
+
+Also, a `strictComparison` method is available for more clarity
+```php
+// Comparisons are strict by default
+ArrayDiffMultidimensional::compare($new, $old);
+
+// This method call is equivalent
+ArrayDiffMultidimensional::strictComparison($new, $old);
+```
