+# Integrazione Doppler
+
+## Obiettivo
+Questo progetto è pronto per l'iniezione dei segreti da Doppler in CI/ambiente runtime.
+
+## Configurazione GitHub richiesta
+1. Crea in Doppler un Project con nome uguale al valore in `DOPPLER_PROJECT`.
+2. Crea in quel project la Config da usare in CI (consigliata: `production`) e assegna i segreti nel modo abituale.
+3. Crea un Service Token **read-only** per GitHub Actions (`token type: service token`), scope al config corretto.
+4. Configura questi segreti/variabili nel repository:
+   - Secret: `DOPPLER_TOKEN`
+   - Variable: `DOPPLER_PROJECT`
+   - Variable: `DOPPLER_CONFIG`
+
+## Stato attuale repo
+- `DOPPLER_PROJECT` impostato a: `Sentinel`
+- `DOPPLER_CONFIG` impostato a: `production`
+
+## Workflow pronto
+È stato aggiunto `.github/workflows/doppler-check.yml`.
+
+### Come usarlo
+- Apri la pagina *Actions* della repo e lancia manualmente `doppler-check`.
+- Se `DOPPLER_TOKEN`, `DOPPLER_PROJECT` e `DOPPLER_CONFIG` sono corretti, il workflow prova il fetch dei segreti Doppler.
+
+## Comandi GitHub (facoltativi)
+
+```bash
+gh variable set DOPPLER_PROJECT --body "Sentinel" --repo max23468/Sentinel
+gh variable set DOPPLER_CONFIG --body "production" --repo max23468/Sentinel
+
+gh secret set DOPPLER_TOKEN --body "<service_token_read_only>" --repo max23468/Sentinel
+```
+
+Sostituisci `<service_token_read_only>` con il token reale del Service Token Doppler.
