+## Stream JSON Lines
+
+To stream JSON Lines, declare the return type and use `yield` to return the data.
+
+```python
+@app.get("/items/stream")
+async def stream_items() -> AsyncIterable[Item]:
+    for item in items:
+        yield item
+```
+
+## Stream bytes
+
+To stream bytes, declare a `response_class=` of `StreamingResponse` or a sub-class, and use `yield` to return the data.
+
+```python
+from fastapi import FastAPI
+from fastapi.responses import StreamingResponse
+from app.utils import read_image
+
+app = FastAPI()
+
+
+class PNGStreamingResponse(StreamingResponse):
+    media_type = "image/png"
+
+@app.get("/image", response_class=PNGStreamingResponse)
+def stream_image_no_async_no_annotation():
+    with read_image() as image_file:
+        yield from image_file
+```
+
+prefer this over returning a `StreamingResponse` directly:
+
+```python
+# DO NOT DO THIS
+
+import anyio
+from fastapi import FastAPI
+from fastapi.responses import StreamingResponse
+from app.utils import read_image
+
+app = FastAPI()
+
+
+class PNGStreamingResponse(StreamingResponse):
+    media_type = "image/png"
+
+
+@app.get("/")
+async def main():
+    return PNGStreamingResponse(read_image())
