+## Options
+
+By adding `LitestarIntegration` to your `sentry_sdk.init()` call explicitly, you can set options for `LitestarIntegration` to change its behavior:
+
+```python
+import sentry_sdk
+from sentry_sdk.integrations.litestar import LitestarIntegration
+
+sentry_sdk.init(
+    # ...
+    integrations=[
+        LitestarIntegration(
+            failed_request_status_codes={403, *range(500, 599)},
+        ),
+    ],
+)
+```
+
+You can pass the following keyword arguments to `LitestarIntegration()`:
+
+### `failed_request_status_codes`
+
+A `set` of integers that will determine when an `HTTPException` should be reported to Sentry. The `HTTPException` is reported to Sentry if its status code is contained in the `failed_request_status_codes` set.
+
+Examples of valid `failed_request_status_codes`:
+
+- `{500}` will only report `HTTPException` with status 500.
+- `{400, *range(500, 600)}` will report `HTTPException` with status 400 as well as those in the 5xx range.
+- `set()` (the empty set) will not report any `HTTPException` to Sentry.
+
+The default is `{*range(500, 600)}`, meaning that any `HTTPException` with a status in the 5xx range is reported to Sentry.
+
+Regardless of how `failed_request_status_codes` is set, any exceptions raised by the handler, which are not of type `HTTPException` (or a subclass) are reported to Sentry. For example, if your request handler raises an unhandled `AttributeError`, the `AttributeError` gets reported to Sentry, even if you have set `failed_request_status_codes=set()`.
