-# How to update the CLI project
-
-The Angular CLI default setup is updated using `ng update`.
-Any necessary file changes will be done automatically through migration schematics.
-
-In the `cli` folder, update the Angular CLI depedencies to the latest version:
-
-```
-ng update @angular/cli --next
-```
-
-Then update the Angular Framework dependencies to the latest version:
-
-```
-ng update @angular/core --next
-```
-
-Commit any changes to the `cli` folder to the repository.
