+## Generators helpers
+
+If you have some (a)sync generators, you can wrap them with the appropriate wrapper:
+
+```ts
+import { wrap, awrap } from 'iterator-helper';
+
+function* generateNumbers() {
+  yield 1;
+  yield* [2, 3, 4];
+}
+
+// wrap for sync generators, awrap for async generators.
+generateNumbers = wrap(generateNumbers);
+
+// It works!
+generateNumbers().filter(e => e % 2 === 0).toArray();
+```
