+### Verifying a UUID
+
+To verify whether a given value is a UUID, use the `is` function.
+
+```javascript
+console.log(uuid.is('75442486-0878-440c-9db1-a7006c25a39f'));
+// => true
+```
+
+If you want to perform the verification on your own, use the `regex` property.
+
+```javascript
+console.log(uuid.regex);
+```
