+This library provides a convenient and extensible way to get an I/O stream pair to an URL – supporting various schemes, such as TCP, TTY, BLE, and EA.
 
 `Foundation` comes with `getStreamsToHost(withName:port:inputStream:outputStream:)`,
 which is clumsy to use and limited to TCP. `CornucopiaStreams` adds support for communicating with TTYs, external accessories
 (using the `ExternalAccessory` framework), and Bluetooth Low Energy (BLE) devices (using the `CoreBluetooth` framework).
 
-_Unfortunately, Linux support is not complete yet. Apart from the missing `ExternalAccessory` and `CoreBluetooth` infrastructure
-(which, at least in the BLE case, could be substituted), the `Stream` class is missing the convenience accessor `Stream.getStreamsToHost`_.
+On non-Apple-platforms, only TCP and TTY are supported, as both `ExternalAccessory` and `CoreBluetooth` are private Apple frameworks – it might be interesting to evaluate [BluetoothLinux](https://github.com/PureSwift/BluetoothLinux).
