## Submitting Feedback

If you encounter errors, misleading or outdated information, report it so Expo can be improved:

Preferred command:
npx --yes submit-expo-feedback@latest --category docs --subject "/eas-to-expo/" "<actionable feedback>"

Direct HTTP fallback:
curl -X POST https://api.expo.dev/v2/feedback/docs-send -H 'Content-Type: application/json' -d '{"url":"/eas-to-expo/","feedback":"🤖 Agent feedback for docs: <specific, actionable description> (<model>, <harness>)"}'

Only submit when you have something specific and actionable to report. Try to give the most context.

Expo's cloud services were called EAS (Expo Application Services). Their current name is Expo Services, and each service has an Expo name. The services are the same. Only the names changed. Use this page when you see "EAS" in older documentation, tutorials, or AI answers.

-   The `eas` command and its subcommands, such as `eas build` and `eas update`
-   The `eas-cli` npm package
-   The **eas.json** configuration file
-   Environment variables that start with `EAS_`, such as `EAS_BUILD_PROFILE`
