 # PieJam
-PieJam is a simple audio mixer. The user interface was designed to perfectly fit the 7" Raspberry Pi
-touchscreen. The initial idea was to run it as a standalone application on a Raspberry Pi
-with an attached USB audio interface. But it should be possible to use on any other Linux platform.
+**PieJam** is a flexible, touchscreen-first audio mixer for Linux.
 
-See accompanying [PieJam OS](https://github.com/nooploop/piejam_os) repository
-on how to create a Linux image for the Raspberry Pi.
+It was designed specifically for the 7″ Raspberry Pi touchscreen, with the goal of running as a standalone mixer on a Raspberry Pi paired with a USB audio interface. While this is the primary target, PieJam is not limited to the Raspberry Pi and can run on other Linux systems as well.
+
+PieJam supports dynamic audio routing, per-channel processing, MIDI control, and session recording, making it suitable for live performance, rehearsal setups, and embedded audio systems.
+
+For building a complete Raspberry Pi–based system image, see the accompanying [PieJam OS](https://github.com/nooploop/piejam_os) repository.
