5. Template selection
6. Library search and installation
7. Additional features setup
8. Profile saving option

$3

`bash
ng-init check
`

Displays current versions of Node.js, npm, nvm, and Angular CLI.

$3

#### List all saved profiles

`bash
ng-init profile list
`

#### Show profile details

`bash
ng-init profile show
`

#### Delete a profile

`bash
ng-init profile delete
`

#### Export a profile

`bash
ng-init profile export
`

Example:
`bash
ng-init profile export my-enterprise-setup ./enterprise-profile.json
`

#### Import a profile

`bash
ng-init profile import
`
