 ##### A note on npm scenarios with lockfiles
 
-Lockfiles are ignored by `ember-try`. (`yarn` will run with `--no-lockfile` and `npm` will be run with `--no-shrinkwrap` and `pnpm` will be run with `--frozen-lockfile=false --no-lockfile`).
+Lockfiles are ignored by `ember-try`. (`yarn` will run with `--no-lockfile` and `npm` will be run with `--no-shrinkwrap` and `pnpm` will be run with `--no-lockfile`).
 When testing various scenarios, it's important to "float" dependencies so that the scenarios are run with the latest satisfying versions of dependencies a user of the project would get.
