# Slack: create/edit an app from an App Manifest — Your Apps → Create New App → From an app manifest; or app → Features → App Manifest

## Steps
1. For a new app: Your Apps → "Create New App" → choose "From an app manifest" (instead of "From scratch").
2. Select the workspace, paste or upload the YAML/JSON manifest, then confirm creation.
3. For an existing app: open it → Features → "App Manifest" to view/edit the current manifest and save changes.

## End state
The app's configuration (scopes, features, display info) matches the manifest just applied; the App Manifest page reflects the saved YAML/JSON.
