+# Anmeldung_v2
+
+Kleine Flask-Webapp, um einen papierbasierten Anmeldebogen durch ein Formular zu ersetzen und die Eingaben in einer SQLite-Datenbank zu speichern.
+
+Installieren:
+
+```bash
+python3 -m venv .venv
+source .venv/bin/activate
+pip install -r requirements.txt
+```
+
+DB initialisieren und Beispiel-Fragen anlegen:
+
+```bash
+python init_db.py
+```
+
+App starten:
+
+```bash
+python app.py
+```
+
+Das Formular ist dann unter http://127.0.0.1:5000/ erreichbar.
