+# Gridseed WebGUI
+
+Ein modernes Web-Interface für den Betrieb von Gridseed ASIC Minern am Raspberry Pi 1 (oder neuer). Inspiriert von Klassikern wie MinePeon und Scripta, aber mit moderner Technologie und Optik.
+
+## Features
+
+- **Dashboard:** Echtzeit-Überwachung von Hashrate, Hardware-Fehlern, Shares und Temperaturen.
+- **Visualisierung:** Live-Graph der Hashrate und übersichtliche Status-Karten.
+- **Steuerung:** Neustart des Miners und Anpassung der Konfiguration über das Web-Interface.
+- **Modern UI:** Responsive Dark-Mode Design basierend auf Bootstrap 5.
+- **Leichtgewichtig:** Optimiert für Raspberry Pi 1 (Python Flask Backend, kein Docker notwendig).
+
+## Voraussetzungen
+
+- Raspberry Pi (ab Version 1)
+- Python 3.7+
+- Installierter `cgminer` mit Gridseed-Support (muss separat installiert werden, z.B. dmaxl's fork).
+
+## Installation
+
+1. Repository klonen:
+   ```bash
+   git clone <URL_ZUM_REPO> /opt/gridseed-gui
+   cd /opt/gridseed-gui
+   ```
+
+2. Abhängigkeiten installieren & Starten:
+   Das `start_gui.sh` Skript kümmert sich um das Python Virtual Environment.
+   ```bash
+   ./start_gui.sh
+   ```
+
+3. Zugriff:
+   Öffnen Sie im Browser `http://<IP-DES-PI>:5000`
+
+## Konfiguration
+
+### cgminer Setup
+Damit die GUI mit dem Miner kommunizieren kann, muss der `cgminer` mit API-Support gestartet werden.
+Die GUI erwartet, dass sie die Konfigurationsdatei `cgminer.conf` lesen und schreiben kann.
+
+Starten Sie Ihren Miner idealerweise so:
+```bash
+cgminer -c /opt/gridseed-gui/cgminer.conf
+```
+
+Stellen Sie sicher, dass in der `cgminer.conf` folgende API-Einstellungen gesetzt sind (passiert automatisch bei Nutzung der Standard-Config):
+```json
+"api-listen": true,
+"api-allow": "W:127.0.0.1"
+```
+
+### Autostart
+Um die GUI beim Booten zu starten, fügen Sie einen Eintrag in die `/etc/rc.local` oder erstellen Sie einen systemd Service.
+
+**Systemd Beispiel (`/etc/systemd/system/gridseed-gui.service`):**
+```ini
+[Unit]
+Description=Gridseed Web GUI
+After=network.target
+
+[Service]
+User=pi
+WorkingDirectory=/opt/gridseed-gui
+ExecStart=/opt/gridseed-gui/start_gui.sh
+Restart=always
+
+[Install]
+WantedBy=multi-user.target
+```
+
+## Screenshots
+
+Das Interface bietet eine übersichtliche Seitenleiste und ein Dashboard im Dark-Mode.
