+## Starta Applikationen
+
+För att starta applikationen i utvecklingsläge:
+
+```bash
+cargo tauri dev
+```
+
+### Felsökning: Linux (Wayland) & "Error 71"
+Om du använder Linux med Wayland (t.ex. GNOME eller KDE Plasma) kan du stöta på "Error 71 (Protocol error)" vid start. Detta är en känd bugg relaterad till WebKitGTK och hårdvaruacceleration.
+
+**Lösning:**
+Kör applikationen med inaktiverad kompositering:
+
+```bash
+WEBKIT_DISABLE_COMPOSITING_MODE=1 cargo tauri dev
+```
+
+Alternativt för vissa NVIDIA-konfigurationer:
+```bash
+__NV_DISABLE_EXPLICIT_SYNC=1 cargo tauri dev
+```
+
 ### Linux-beroenden (Ubuntu/Debian)
 För att kompilera Tauri på Linux krävs följande bibliotek:

 * `src-tauri/src/main.rs`: Entry point. Innehåller logik för System Tray.
 * `src-tauri/tauri.conf.json`: Konfiguration för fönster och byggprocess.
 
+## Loggning
+
+Applikationen har inbyggt stöd för loggning för att underlätta felsökning.
+
+*   **Plats:** Loggfiler sparas i en mapp som heter `loggs` som ligger i samma katalog som den körbara filen.
+*   **Filnamn:** En loggfil skapas per dag och döps efter dagens datum (t.ex. `2024-01-18.log`).
+*   **Format:** Loggarna innehåller tidsstämpel, loggnivå (INFO, DEBUG, ERROR), modul/funktion samt meddelandet. Exempel:
+    `[2024-01-18 10:00:00][INFO][ai_translater_client::main] Application started`
+*   **Loggade händelser:** Applikationsstart, system tray-händelser, felmeddelanden och annan viktig information loggas.
