# Modules KVision consists of both required and optional functionality. Modules can be added as dependencies in `build.gradle.kts` file. All modules which include CSS stylesheets require explicit initialization. This also applies to the core module. This initialization ensures a predictable order in which all styles will be applied. The initialization is performed by adding dedicated module objects as parameters to the `startApplication()` function. ```kotlin fun main() { startApplication( ::App, js("import.meta.webpackHot").unsafeCast(), BootstrapModule, BootstrapCssModule, FontAwesomeModule, TomSelectModule, DatetimeModule, BootstrapUploadModule, CoreModule ) } ``` {% hint style="info" %} Some modules include more than one, optional initializers. E.g. `kvision-tabulator` module includes mandatory `TabulatorModule` but also `TabulatorCssBootstrapModule` , `TabulatorCssBulmaModule`, `TabulatorCssMaterializeModule`, `TabulatorCssMidnightModule`, `TabulatorCssModernModule`, `TabulatorCssSemanticModule`, `TabulatorCssSimpleModule` and `TabulatorCssStandardModule` for all CSS styles supported by the Tabulator component. {% endhint %} This is the current list of available modules. | Module | Description | | ------------------------------------------------------------------------------------------------------------------------------- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------ | | kvision | Core module required for all applications. | | [kvision-bootstrap](https://kvision.gitbook.io/kvision-guide/3.-optional-ui-functionality-via-modules/bootstrap) |
