Describe the problem

It seems that installing snaplet and importing defineConfig might no longer be feasible.

import { defineConfig } from "snaplet";

export default defineConfig({
  transform: {
    public: {
      User: () => {
        return {
          email: 'my-new-email@example.org',
        };
      },
    },
  },
});

Is it still possible to select and transform through other methods?

Transformation via npx @snaplet/snapshot snapshot capture -t auto will transform wholesale

Describe the improvement

Update the documentation to inform users on how to select and transform data using the configuration. Alternatively, clarify if this functionality is no longer available.
