 - All the files in `src/lib`, unless you [configure](#configuration-package) custom `include`/`exclude` options. Svelte components will be preprocessed, TypeScript files will be transpiled to JavaScript.
 - Type definitions (`d.ts` files) which are generated for Svelte, JavaScript and TypeScript files. You need to install `typescript >= 4.0.0` and `svelte2tsx >= 0.4.1` for this. Type definitions are placed next to their implementation, hand-written `d.ts` files are copied over as is. You can [disable generation](#configuration-package), but we strongly recommend against it.
-- A `package.json` that copies the `name`, `version`, `description`, `keywords`, `homepage`, `bugs`, `license`, `author`, `contributors`, `funding`, `repository`, `dependencies`, `private`, `files` and `publishConfig` fields from the root of the project, and adds a `"type": "module"` and an `"exports"` field
+- A `package.json` copied from the project root without the `"scripts"` field and adds a `"type": "module"`. An `"exports"` field will also be added if it's not defined in the original file.
 
 The `"exports"` field contains the package's entry points. By default, all files in `src/lib` will be treated as an entry point unless they start with (or live in a directory that starts with) an underscore, but you can [configure](#configuration-package) this behaviour. If you have a `src/lib/index.js` or `src/lib/index.svelte` file, it will be treated as the package root.
