+Welcome to the guest-focused documentation hub. Start with any of the guides below—each article is available in English and German:
+
+- [Quick Start](./getting-started) – Install the app, join an event, and learn the core gestures.
+- [Upload Workflow](./uploading-photos) – Capture, edit, and upload photos with background sync.
+- [Offline Mode & Sync](./offline-sync) – Keep contributing when connectivity drops and ensure nothing gets lost.
+- [Privacy & Support](./privacy-and-support) – Understand what data is stored and how to reach support.
+
+### How to use these docs
+- **Search**: Use the in-app search bar or the offline search inside the app settings. Keywords such as “upload limit” or “share link” work well.
+- **Language toggle**: Switch between EN/DE via the globe icon embedded in every article.
+- **Contextual links**: Many UI screens provide a `?` icon that deep-links to the relevant section here.
