Problems creating a Netlify Integration

I’m trying to create a Netlify Integration capable of injecting an edge function. I am following the instructions here: Create a new extension | 2.5.2

As instructed I run the following command:

pnpm create @netlify/sdk@1.8.7
? Where do you want to create the integration? .
? What is the slug of the integration? (e.g. my-integration) netlify-integration-alt
? Summarize what your integration does. This will be shown on the integration's card on the Integrations page.
? Which boilerplate should be included? Edge Function Injection (beta)
? What level will this integration be installed on? site (recommended for Build Event Handlers, Edge Functions and
Functions)
? Would you like to configure VS Code to use Edge Functions? no
? Which package manager do you want to use? pnpm
? Do you want to create or link a Netlify site to your integration? This will help you test your integration and
will be used to host your integration. skip

Initialising integration...
Error: The "netlify-integration" CLI has been renamed to "netlify-extension".
	Please use the new "netlify-extension" command instead.
node:internal/errors:984
  const err = new Error(message);
              ^

Error: Command failed: pnpm netlify-integration init -s netlify-integration-alt -d "" -l site -p site:read,site:write
Error: The "netlify-integration" CLI has been renamed to "netlify-extension".
	Please use the new "netlify-extension" command instead.

I also tried the same command, but using @latest instead of @1.8.7 and this runs without any errors, but then when I try to actually use the deployed integration, it complains about a missing integration.yaml. But it seems as though the new tooling creates an extension.yaml instead.

Am I following the right instructions? Any suggestions to avoid these errors?

The docs are not released to reflect the latest changes yet. We’re in the middle of a major upgrade. Unless you need to do something that excplicitly requires an Integration (now renamed to Extension), you can probably use a Build Plugin (that’s what more users need).
