+
+On Ubuntu-ish systems (not tested on Debian but may work):
+
+```
+sudo apt update && sudo apt install libwebkit2gtk-4.0-dev \
+    build-essential \
+    curl \
+    wget \
+    libssl-dev \
+    libgtk-3-dev \
+    libappindicator3-dev \
+    patchelf \
+    librsvg2-dev```
+
+
+
+## Getting started
+
+1. Start Sapper([docs](https://sapper.svelte.dev/docs/)) -> `yarn run dev`
+2. Start Tauri([docs](https://tauri.studio/en/)) in another terminal -> `yarn tauri dev`
+3. Start validator-api locally, or override `validator-urls` in `index.svelte`
+
+## Getting around
+
++ Frontend -> `tauri-client/`
+  + logic -> `tauri-client/src/routes/index.svelte`
+  + assets -> `tauri-client/static`
++ Backend -> `tauri-client/src/src-tauri`
+
+## Build standalone app
