+
+## Voraussetzungen
+- API erreichbar: `GET /import/wiki/health` (Status `ok`)
+- .env:
+  - `API_BASE_URL=http://localhost:8000`
+  - `WIKI_BOT_USER`, `WIKI_BOT_PASSWORD`
+  - optional: `EXERCISE_COLLECTION=exercises`
+
+## Smoke-Test (3 Läufe)
+```bash
+python3 wiki_importer.py --title "Affenklatschen" --category "Übungen" --smoke-test
+```
+
+## Vollimport
+```bash
+python3 wiki_importer.py --all
+# optional:
+python3 wiki_importer.py --all --category "Übungen"
+python3 wiki_importer.py --all --dry-run
+```
+
+## Idempotenz-Logik
+- external_id = `mw:{pageid}`
+- Fingerprint (sha256) über: `title, summary, execution, notes, duration_minutes, capabilities, keywords`
+- Entscheid:
+  - not found → create
+  - fingerprint gleich → skip
+  - fingerprint ungleich → update (+ `imported_at`)
+
+## Mapping (Wiki → Exercise)
+- Schlüsselworte → `keywords` (`,`-getrennt, getrimmt, dedupliziert)
+- Hilfsmittel → `equipment`
+- Disziplin → `discipline`
+- Durchführung/Notizen/Vorbereitung/Methodik → `execution`, `notes`, `preparation`, `method`
+- Capabilities → `capabilities` (Level 1..5) + Facetten (`capability_ge1..5`, `capability_eq1..5`, `capability_keys`)
+- Metadaten → `external_id`, `source="mediawiki"`, `imported_at`
+
+## Troubleshooting
+- 404 bei `/import/wiki/info?...`: prüfe Prefix (kein Doppelprefix), Titelvarianten
+- 401 Login: echte User-Creds verwenden
+- 502 Upstream: `WIKI_API_URL`/TLS prüfen; Timeouts/Retry/Throttle (`WIKI_TIMEOUT`, `WIKI_RETRIES`, `WIKI_SLEEP_MS`)
