+### Options
+* `--path` - Specifies the directory where you want to create the project, if different from the current directory. The directory must be empty.
+* `--copy-from` - Specifies a directory which contains an existing NativeScript project. If not set, the NativeScript CLI creates the project from the default hello-world template.
+
+### Attributes
+* `<Path To Package.json File>` is the path to a package.json file or directory that contains a package.json file. <% if(isConsole) { %>For more information about the `package.json` specification, see https://github.com/NativeScript/nativescript-cli/blob/master/PLUGINS.md#packagejson-specification<% } %>. If the path to `package.json` is not specified, the NativeScript CLI searches for `package.json` in the current directory.
