+## Automated CI/CD
+
+An **EAS Cloud Workflow** (`mobile/.eas/workflows/create-builds.yml`) automates production builds and iOS submission:
+
+- **Path filtering:** The workflow only triggers on pushes to `main` that include changes inside the `mobile/` directory.  Backend-only or documentation-only changes do not trigger a mobile build.
+- **Build:** Both iOS and Android production builds run in parallel on EAS Build.
+- **Auto-submit (iOS):** After a successful iOS build, the workflow automatically submits the binary to **App Store Connect** using the credentials configured in `eas.json` (`submit.production.ios`).  The build then appears in **TestFlight** for internal testing and can be promoted to the App Store from App Store Connect.
+
+> **Prerequisite:** An App Store Connect API Key must be configured in EAS for non-interactive submission.  See [Troubleshooting → "Session expired"](#session-expired-local-session-during-ios-build) below for setup instructions.

+## CI/CD
+
+An EAS Cloud Workflow (`mobile/.eas/workflows/create-builds.yml`) runs automatically when changes inside `mobile/` are pushed to `main`:
+
+1. **Path filtering** — only commits that modify files under `mobile/` trigger a build; backend-only changes are skipped.
+2. **Parallel builds** — iOS and Android production builds run at the same time on EAS Build.
+3. **Auto-submit to Apple** — after the iOS build succeeds, the workflow submits the binary to App Store Connect (TestFlight) using the credentials in `eas.json` → `submit.production.ios`.
+
+> An [App Store Connect API Key](https://docs.expo.dev/app-signing/app-credentials/#app-store-connect-api-key) must be configured in EAS (`eas credentials`) for non-interactive submission.

 ## Configuration
 
 No code changes are needed to point the app at a different server.  The server URL is entered by the user on the login screen and stored in the device's secure store.
