+  HTTP client for Sentry based on Req.
+
+  This client implements the `Sentry.HTTPClient` behaviour.
+  It's based on the [Req](https://github.com/wojtekmach/req) Elixir HTTP client,
+  which is an *optional dependency* of this library. If you wish to use another
+  HTTP client, you'll have to implement your own `Sentry.HTTPClient`. See the
+  documentation for `Sentry.HTTPClient` for more information.
