+### Getting a UUID from a string
+
+From time to time you need an identifier that looks like a UUID, but is actually inferred from a string. For that, use the `fromString` function.
+
+```javascript
+console.log(uuid.fromString('the native web'));
+// => 'cc762e69-089e-4239-8b06-1ab26a005319'

+
+### Getting the empty UUID
+
 If you need a UUID that consists only of zeros, use the `empty` function.
