# Services.yaml {#servicesyaml}

<!-- TODO: no Markdown rendering for "versionadded" -->

Services can be configured in this file. TYPO3 uses it for:

-   [Dependency Injection](https://docs.typo3.org/permalink/t3coreapi:configure-dependency-injection-in-extensions@11.5)
-   [Event Listeners](https://docs.typo3.org/permalink/t3coreapi:eventdispatcherregistration@11.5)
-   Command Controllers (see [Feature: #89139 - Add dependency injection support for console commands](https://docs.typo3.org/c/typo3/cms-core/main/en-us/Changelog/10.3/Feature-89139-AddDependencyInjectionSupportForConsoleCommands.html))
-   [Registering a widget with the dashboard](https://docs.typo3.org/c/typo3/cms-dashboard/11.5/en-us/Configuration/WidgetRegistration.html#register-new-widget)

A typical `Configuration/Services.yaml` may look like this:

**EXT:my_extension/Configuration/Services.yaml**

```yaml
services:
  _defaults:
    autowire: true
    autoconfigure: true
    public: false

  T3docs\Examples\:
    resource: '../Classes/*'
    exclude: '../Classes/Domain/Model/*'

  MyVendor\MyExtension\LinkValidator\LinkType\ExampleLinkType:
    tags:
      -  name: linkvalidator.linktype

```
