+## UX Principles
+
+- **Opinionated.** There should never be two ways to do the same thing.
+- **Intuitive.** If a feature needs a description to explain it,
+  the feature has failed.
+- **Simple.** No useless buttons that always need to be pressed.
+
+## UI Design
+
+The UI design is based on Material 3.
+
+## Development Setup
+
+### Nix
+
+[Enable flakes](https://nixos.wiki/wiki/Flakes#Enable_flakes), then start the development shell using
+
+```shell
+nix develop
+```
+
+You may need to run through some additional setup to get Rust running inside IntelliJ.
+
+### Other platforms
+
+- NodeJS >=18.16
+- Python >=3.10
+- Rust Stable (For Tauri Development)
+
+I know, python in JS projects is extremely annoying, unfortunately,
+it seems to be the only platform that offers a functional
+way to subset variable woff2 fonts with ligatures.
+
+In other words, either have python as a development dependency or
+serve a 3.5MB icons font of which 99.5% is completely unused.
