+## Usage
+
+### without_terminate
+
+`without_terminate` is a generator that it will not yield after the timeout,
+but it will not raise an exception.
+
+```python
+from timeout_iterator import without_terminate
+results = []
+for i in without_terminate(range(10), seconds=0.3):
+    results.append(i)
+    time.sleep(0.1)
+
+assert results == [0, 1, 2]
+```
+
+### terminate
+
+`terminate` is a generator that it will raise an exception after the timeout.
+
+```python
+from timeout_iterator import terminate
+try:
+    results = []
+    for i in terminate(range(10), seconds=0.3):
+        results.append(i)
+        time.sleep(0.1)
+except TimeoutError:
+    pass
+
+assert results == [0, 1, 2]
