+### Important notes
+
+- If you need support for another platform, please fill an [issue](https://github.com/ircam-ismm/node-web-audio-api/issues) and we will see what we can do.
+
+- All provided Linux binaries are built with the `jack` flag, which should work either with properly configured [Jack](https://jackaudio.org/) or [pipewire-jack](https://pipewire.org/) backends (...working on interactive / real-time audio, this is our requirements and thus what we _de facto_ support). If this is a limitation for you, please fill an [issue](https://github.com/ircam-ismm/node-web-audio-api/issues) and we will see what we can do.
