1. Click Meta Developer Portal on the Instagram Feed card, create a Meta app with the Instagram product, and add https://<your-site>/admin/integrations?redirect=instagram_callback as a valid OAuth redirect.
2. Copy the app's ID and secret into Instagram - App ID and Instagram - App Secret on the card.
3. Close and reopen the card; the Connect Instagram button now appears (until both fields are filled it shows Enter your App ID and App Secret above before connecting).
4. Click Connect Instagram, log in to Instagram and approve access. You are returned to the Integrations page with Instagram connected successfully! and the card shows Connected as @yourusername.
5. In the page editor add the Instagram Feed module (Social category) to any page and choose Number of Posts, Columns, Spacing, captions and whether posts link to Instagram.

Use Disconnect on the card to remove the connection.
