-## Languages
+## What the site is for
 
-`index.md` is the English page at `/`, `de/index.md` the German page at `/de/`.
-Both carry `hreflang` alternates and a language switch; the layout picks its few
-interface strings from the page's `lang`. A content change to one page belongs in
-the other in the same change. `check_site.rb` fails if the German page, its
-alternates or its search terms go missing, and if either page or `llms.txt`
-loses the stack section (the terms are listed in `STACK` in that script).
+opentaberna.de is a customer landing page. OpenTaberna is free; vaultops sells
+setup on the customer's server, hosting in Germany and custom storefronts. Every
+call to action is a pre-filled `mailto:` link, so there is no form, no third party
+and no cookie banner. Nothing may load from another origin.
+
+## Pages and where their content lives
+
+| URL | Source | Content |
+|---|---|---|
+| `/`, `/de/` | `index.md`, `de/index.md` → `_includes/landing.html` | copy in `_data/i18n.yml` (`en`, `de`) |
+| `/developers/`, `/de/entwickler/` | `developers/index.md`, `de/entwickler/index.md` | Markdown in the page |
+| `/impressum/`, `/datenschutz/` | `impressum/index.md`, `datenschutz/index.md` | German only |
+
+Both landing pages render one template from `_data/i18n.yml`, so their structure
+cannot drift; the mail subjects and bodies live there too. Pages that exist in
+both languages set `lang` and `alt_url`, which drive the `hreflang` alternates and
+the language switch. A content change to one language belongs in the other in the
+same change.
+
+The comparison with Shopware and Shopify cites the vendors' own pricing pages.
+Re-check those figures before changing the table and update the "as published"
+month.
+
+## Product screenshots
+
+`assets/img/*.webp` are screenshots of the real `frontend` and `admin_frontend`
+running against the `fastapi` dev stack with the sample catalogue (`seed.py`) and
+illustrated product images, taken at 1440×900 with 2× pixel density and
+converted with `cwebp -q 78 -resize 1600 0`. `assets/img/og.jpg` is the 1200×630
+social preview cropped from the storefront screenshot.
+
+## Checks
+
+`scripts/check_site.rb` fails if any page, its language pairing or footer legal
+links go missing; if the landing sections change order or lose their email calls
+to action, the wiki link or the comparison sources; if the Impressum or privacy
+policy lose their required details; if any page loads a resource from another
+origin or a screenshot lacks alt text; if a page links to the not-yet-existing
+demo shop; if the home pages lose their search terms (English title, description
+and H1; German description and H1); and if the developer pages or `llms.txt` lose
+the stack terms listed in `STACK`.

+    eyebrow: Questions
+    title: Before you write to us
+    items:
+      - q: Is OpenTaberna really free?
+        a: Yes. Every part is open source under the Apache-2.0 licence. You can run it, change it and even sell it on. You only pay us if you want help with setup, hosting or a custom storefront.
+      - q: What does hosting cost?
+        a: That depends on the size of your shop. Tell us what you sell and roughly how many orders you expect, and we send you a fixed price.
+      - q: Can I move away later?
+        a: Yes. The code is open and your data sits in a standard PostgreSQL database, so any developer can take over. If we host your shop, you can take a full copy with you.
+      - q: What do I need to run it myself?
+        a: A Linux server with Docker, a domain, a Stripe account for payments and, if you ship with DHL, a DHL business account. The wiki walks you through the rest.
+      - q: What can you build for the storefront?
+        a: Anything from adapting the included storefront to your brand to a completely new design. Both run on the same back office and API.
+      - q: Is it ready for my shop?
+        a: OpenTaberna is young. Today it covers catalogue, Stripe checkout, stock, orders, returns, DHL shipping and accounting documents. Tell us what you sell and we will tell you honestly whether it fits.

+      - q: Ist OpenTaberna wirklich kostenlos?
+        a: Ja. Jeder Teil ist Open Source unter der Apache-2.0-Lizenz. Du darfst ihn betreiben, verändern und sogar weiterverkaufen. Du zahlst uns nur, wenn du Hilfe bei Einrichtung, Hosting oder einer eigenen Storefront willst.
+      - q: Was kostet das Hosting?
+        a: Das hängt von der Größe deines Shops ab. Schreib uns, was du verkaufst und wie viele Bestellungen du ungefähr erwartest, und du bekommst einen festen Preis.
+      - q: Kann ich später wechseln?
+        a: Ja. Der Code ist offen und deine Daten liegen in einer normalen PostgreSQL-Datenbank, also kann jede Entwicklerin und jeder Entwickler übernehmen. Wenn wir deinen Shop hosten, bekommst du eine vollständige Kopie mit.
+      - q: Was brauche ich, um ihn selbst zu betreiben?
+        a: Einen Linux-Server mit Docker, eine Domain, ein Stripe-Konto für Zahlungen und, wenn du mit DHL versendest, ein DHL-Geschäftskundenkonto. Das Wiki führt dich durch den Rest.
+      - q: Was könnt ihr für die Storefront bauen?
+        a: Von der Anpassung der mitgelieferten Storefront an deine Marke bis zu einem komplett neuen Design. Beides läuft auf demselben Backoffice und derselben API.
+      - q: Ist er bereit für meinen Shop?
+        a: OpenTaberna ist jung. Heute deckt es Katalog, Stripe-Checkout, Bestand, Bestellungen, Retouren, DHL-Versand und Buchhaltungsbelege ab. Schreib uns, was du verkaufst, und wir sagen dir ehrlich, ob es passt.

+    title: Erzähl uns von deinem Shop.
+    text: Schreib ein paar Zeilen dazu, was du verkaufst. Wir antworten persönlich, meist innerhalb von zwei Werktagen.

+    eyebrow: Wer dahintersteht
+    title: Gebaut von zwei Gründern, die es selbst gebraucht haben.
+    text: Wir haben OpenTaberna gestartet, weil Shopware teuer war und sich kaum mit dem verbinden ließ, was wir brauchten. Einrichtung, Hosting und individuelle Storefronts bietet vaultops an.

+  OpenTaberna für Entwickler: ein selbst gehostetes Open-Source-Headless-Shopsystem
+  auf Basis von FastAPI, PostgreSQL, Keycloak und Angular. Repositories, Stack und Doku.

+
+# Ein Open-Source-Headless-Shopsystem, das du lesen, betreiben und ändern kannst.
+{: .page-title}
+
+## Was OpenTaberna ist
+
+Wir haben OpenTaberna gestartet, weil Shopware teuer ist und sich mit kaum etwas
+verbinden ließ, das wir anbinden mussten. Also haben wir eine Open-Source-Alternative
+zu Shopware gebaut. OpenTaberna trennt Storefront, Verwaltung und Backend und stellt
+die Automatisierung in den Mittelpunkt: vom Katalog über Checkout und Lagerbestand bis
+zu Zahlung und Versand.
+
+Es ist ein Headless-Shop von Grund auf und standardmäßig selbst gehostet. Du betreibst
+ihn auf deinen eigenen Servern, wählst Schnittstellen, Dienste und Deployment selbst
+und baust den individuellen Webshop, den dein Geschäft braucht, statt deinen Betrieb
+an ein geschlossenes Produkt anzupassen.
+
+## Woraus es besteht
+
+<ul class="projects">
+  <li class="project">
+    <h3><a href="https://github.com/OpenTaberna/fastapi">fastapi</a></h3>

+
+## Worauf es läuft

+Ein selbst gehosteter E-Commerce-Stack aus bewährten Open-Source-Bausteinen, gestartet
+mit Docker Compose:
+
+- **Backend:** Python und FastAPI, mit asynchronem SQLAlchemy auf PostgreSQL und Redis für Hintergrundjobs.
+- **Storefront und Backoffice:** Angular, angebunden über die API. Es ist headless, du kannst also dein eigenes Frontend mitbringen.
+- **Konten:** Keycloak-Single-Sign-on für Kundschaft und Team.
+- **Zahlung und Versand:** Stripe für Zahlungen, DHL für den Versand.
+- **Dokumente und Dateien:** Paperless-ngx für Buchhaltungsbelege, MinIO als S3-kompatibler Speicher.
+- **Betrieb:** Prometheus, Grafana und OpenTelemetry.

+## What OpenTaberna is
+
+We started OpenTaberna because Shopware is expensive and incompatible with nearly
+everything we needed to connect, so we built an open-source Shopware alternative.
+OpenTaberna separates the storefront, administration and backend, then puts automation
+at the centre: from catalogue and checkout to stock, payment and fulfilment.
+
+It is a headless shop by design and self-hosted by default. You run it on your own
+servers, choose the interfaces, services and deployment around it, and build the
+custom web shop your business needs instead of adapting your operation to a closed
+product.
