+# Lokaler LibreTranslate-Server
+
+LibreTranslate stellt eine HTTP-API auf dem eigenen Rechner bereit. Es werden keine
+Texte an einen externen Übersetzungsdienst gesendet. Die Standardadresse ist
+`http://localhost:5000`.
+
+## Installation unter Linux
+
+Voraussetzung: Python 3.8 oder neuer. In einem Terminal:
+
+```bash
+python3 -m venv ~/.local/share/libretranslate-venv
+~/.local/share/libretranslate-venv/bin/pip install --upgrade pip libretranslate
+~/.local/share/libretranslate-venv/bin/libretranslate
+```
+
+Beim ersten Start werden Sprachmodelle geladen. Für weniger Speicherbedarf kann man
+nur benötigte Sprachen laden, beispielsweise Englisch und Deutsch:
+
+```bash
+~/.local/share/libretranslate-venv/bin/libretranslate --load-only en,de
+```
+
+Der Server bleibt im Terminal aktiv. Anschließend in Renpy Translation Helper im
+Auswahlfeld **Provider** `LibreTranslate (local)` wählen. Die voreingestellte lokale
+URL `http://localhost:5000` übernehmen oder anpassen. Die verfügbaren Sprachpaare
+werden automatisch geladen.
+
+## Nur Englisch und Deutsch nachinstallieren
+
+Wurde ein erster Start ohne `--load-only` abgebrochen, können bereits einige
+unpassende Modelle installiert sein. Den Server mit `Strg+C` beenden und die zwei
+benötigten Richtungen explizit installieren:
+
+```bash
+~/.local/share/libretranslate-venv/bin/argospm update
+~/.local/share/libretranslate-venv/bin/argospm install translate-en_de
+~/.local/share/libretranslate-venv/bin/argospm install translate-de_en
+~/.local/share/libretranslate-venv/bin/libretranslate --load-only en,de
+```
+
+Mit `curl http://127.0.0.1:5000/languages` prüfen, ob sowohl `en` mit Ziel `de`
+als auch `de` mit Ziel `en` aufgelistet wird. Erst dann kann die App diese
+Sprachrichtung anbieten.
+
+## Nutzung durch andere Anwendungen
+
+Sprachen abfragen:
+
+```bash
+curl http://localhost:5000/languages
+```
+
+Einen Text übersetzen:
+
+```bash
+curl -X POST http://localhost:5000/translate \
+  -H 'Content-Type: application/json' \
+  -d '{"q":"Hello world","source":"en","target":"de","format":"text"}'
+```
+
+Für mehrere Texte kann `q` ein Array sein:
+
+```bash
+curl -X POST http://localhost:5000/translate \
+  -H 'Content-Type: application/json' \
+  -d '{"q":["Hello","Good night"],"source":"en","target":"de","format":"text"}'
+```
+
+Die Antwort enthält `translatedText` – bei mehreren Eingaben ebenfalls als Array.
+
+## Hinweis zu AMD-Grafikkarten
+
+LibreTranslate/Argos Translate verwendet regulär die CPU. Die offiziell dokumentierte
+GPU-Beschleunigung setzt CUDA voraus und ist damit für Nvidia vorgesehen. Eine
+AMD-GPU wird in diesem Standard-Setup nicht genutzt; für normale Ren'Py-Dialoge ist
+der CPU-Betrieb dennoch brauchbar.
