+# Funktionsweise
+
+* Passwortgenerierung: Die Anwendung generiert ein 32-stelliges Passwort mit Großbuchstaben, Kleinbuchstaben und Ziffern (entspricht dem Befehl `apg -a 1 -m 32 -n 1 -M NCL`).
+* Zwischenablage: Mit dem Button "In Zwischenablage kopieren" wird das Passwort in die Zwischenablage kopiert.
+* Docker: Der Container enthält nur die Go-Anwendung und keine zusätzliche Linux-Distribution.
+
+
+# Baue die Go-Anwendung
+
+```
+go build -o password-generator ./
+```
+
+# Baue das Docker-Image
+
+```
+docker build -t password-generator .
+```
+
+# Starte den Docker Container
+
+```
+docker run -p 8080:8080 password-generator
+```
