## Set up

Next.js and Node functions use `pagerless/auto`; Edge functions use `withPagerless`.

Store the key with `vercel env add PAGERLESS_KEY production`. Or run `npx pagerless connect` and it finds your services and places the key for you.

## Questions

### Can Pagerless roll back Vercel automatically?

Yes, if your rules set undo to alone. By default it asks first, and approving an undo needs your passkey (Face ID or Touch ID). It then rolls back to the previous deployment.

### Does Pagerless need admin access to Vercel?

It needs a Vercel access token. It is stored encrypted and used only for the fixes listed above. You can skip it: alerts work without it.
