It’s on my list to review it. I suspect most of the steps will stay the same but I will confirm.

You should use `api.container` in your new code, but you can just pass the `container` to your old code like this:

```plaintext
initialize(container) {
   withPluginApi('0.1', api => newCode(api), { noApi: () => oldCode(container) });
}

```

(I doubt I will ever remove `container` from `initialize` BTW. The `api` object just has it for convenience so you don’t have to pass it around).
