 - `package multibucket`: this file is part of the multibucket package
-- `import ( "dagger.io/js/yarn" )`: import a package from the [Dagger Universe](../reference/universe/README.md).
+- `import ( "alpha.dagger.io/js/yarn" )`: import a package from the [Dagger Universe](../reference/universe/README.md).
 - `app: yarn.#Package`: apply the `#Package` definition at the key `app`
 - `&`: also merge the following values at the same key...
