 ## Technology
 
-The game uses [wgpu-rs](https://github.com/gfx-rs/wgpu-rs) for graphics and [winit](https://github.com/tomaka/winit) for windowing.
+The game uses:
+  - [wgpu](https://github.com/gfx-rs/wgpu) for graphics
+  - [winit](https://github.com/rust-windowing/winit) for windowing
+  - [egui](https://github.com/emilk/egui) for debug UI

See the [dedicated wiki page](https://github.com/kvark/vange-rs/wiki/Rendering-Techniques) for our rendering technologies.
