 ## Migrations
 
 This plugin supports Nx migrations and provides necessary version and code updates for Qwik. So instead of bumping plugin version manually in package.json it's recommended to run `nx migrate qwik-nx` command, that includes bumping the version of the qwik-nx plugin, related dependencies and running code migrations.
