+Immersive Virtual Musical Instruments. It relies on the Godot game engine
+and the PureData audio programming language.
 
-Connect to or integrates PureData patches 
 
-Networking 
+## Prerequisites
 
-## Install
-
-
-To run the Pd patches, install gdpd, otherwise you can run PureData 
-on a computer on the same network, which enables live-editing of the sound
-synthesis while the instrument is running.
-
-To render with an OpenXR compatible device (HMD, mobile) install godot-openxr
-
-To render on a stereoscopic (anaglyph, passive in splitscreen, or quadbuffer) display
-install GdScreenVr
+* PureData from [https://puredata.info](https://puredata.info)
+* Godot 4.x from [https://godotengine.org/](https://godotengine.org/), with [OpenXR activated](https://docs.godotengine.org/en/stable/tutorials/xr/setting_up_xr.html)
+* If you want to be able to integrate the audio when releasing your instrument
+    (e.g. in a binary or as an app), install the [Gdpd addon](https://gitlab.univ-lille.fr/ivmi/gdpd)
