--   `angular-ngrx-store` is the template name; It uses the same option name in the [IConfigItem](#iconfigitem) but converts all options names to kebab-case. For example `option: 'Angular Ngrx Store'` will be converted to `angular-ngrx-store` when using the command line
--   `__name__=some-name` and `__model__=some-other-name` are [Replacer Slots](#replacer-slots-or-ireplacerslotquestion) and will be converted to `{ slot: "__name__", slotValue: "some-name" }`
