-# Tauri Git Lite
 
-Eine kleine Git-Desktop-App mit Tauri, Rust und Svelte.
-
-## Funktionen
-
-- Repository per lokalem Pfad öffnen
-- aktuellen Branch, Upstream, Ahead/Behind und Arbeitsbaumstatus anzeigen
-- Branches auflisten und auschecken
-- Branches in den aktuellen Branch mergen
-- Commit-History mit geänderten Dateien anzeigen
-- Explorer-Ansicht mit Ordnerbaum sowie getrackten und ungetrackten Dateien
-- Datei- und Ordner-History direkt aus dem Explorer anzeigen
-- einzelne Dateien stagen, unstagen und wiederherstellen
-- einzelne Dateien oder ganze Ordner aus einem History-Commit wiederherstellen
-- aktuellen Branch auf einen ausgewählten Commit zurücksetzen
-- Commit mit Message erstellen
-- Pull mit Fast-Forward-Strategie
-- Push auf den konfigurierten Upstream
-
-## Entwicklung
-
-```powershell
-npm install
-npm run tauri:dev
-```
-
-Frontend allein:
-
-```powershell
-npm run dev
-```
-
-Checks:
-
-```powershell
-npm run check
-npm run build
-cd src-tauri
-cargo check
-```
-
-## Hinweis
-
-Die App nutzt das lokal installierte `git` CLI. Ein Repository muss daher bereits auf der Maschine vorhanden sein, und Push/Pull verwenden die Credentials, die Git lokal kennt.
