Visit the [project website](https://contao.org) for more information. Contao has been designed as a [Symfony](https://symfony.com) bundle, which can be used to add CMS functionality to any Symfony application. If you do not have an existing Symfony application yet, we recommend using the [Contao managed edition](https://github.com/contao/managed-edition)as basis for your application. Prerequisites ------------- [](#prerequisites) The Contao core bundle has a recipe in the [symfony/recipes-contrib](https://github.com/symfony/recipes-contrib) repository. Be sure to either enable contrib recipes for your project by running the following command or follow the instructions to use the contrib recipe during the installation process. ``` composer config extra.symfony.allow-contrib true ``` Add the `contao-component-dir` to the `extra` section of your `composer.json` file. ``` composer config extra.contao-component-dir assets ``` Installation ------------ [](#installation) Install Contao and all its dependencies by executing the following command: ``` composer require \ contao/core-bundle:4.8.* \ php-http/guzzle6-adapter:^1.1 ``` Note that you can exchange the `php-http/guzzle6-adapter` package with any other [HTTP client implementation](https://packagist.org/providers/php-http/client-implementation). If you already have an HTTP client implementation, you can omit the package entirely. Configuration ------------- [](#configuration) Configure the `DATABASE_URL` in your environment, either using environment variables or by using the [Dotenv component](http://symfony.com/doc/current/components/dotenv.html). Enable ESI in the `config/packages/framework.yaml` file. ``` framework: esi: true ``` Add the Contao routes to your `config/routing.yaml` file, and be sure to load the `ContaoCoreBundle` at the very end, so the catch-all route does not catch your application routes. ``` ContaoCoreBundle: resource: "@ContaoCoreBundle/config/routes.yaml" ``` Edit your `config/security.yaml` file and merge all the `providers`, `encoders`, `firewalls` and `access_control`sections: ``` security: password_hashers: Contao\User: auto Symfony\Component\Security\Core\User\PasswordAuthenticatedUserInterface: auto providers: contao.security.backend_user_provider: id: contao.security.backend_user_provider contao.security.frontend_user_provider: id: contao.security.frontend_user_provider firewalls: contao_backend: request_matcher: contao.routing.backend_matcher provider: contao.security.backend_user_provider user_checker: contao.security.user_checker switch_user: true login_throttling: ~ webauthn: authentication: enabled: true profile: contao_backend routes: options_path: /_contao/login/webauthn/options result_path: /_contao/login/webauthn/result login_link: check_route: contao_backend_login_link signature_properties: [username, lastLogin] success_handler: contao.security.authentication_success_handler contao_login: remember_me: false logout: path: contao_backend_logout contao_frontend: request_matcher: contao.routing.frontend_matcher provider: contao.security.frontend_user_provider user_checker: contao.security.user_checker access_denied_handler: contao.security.access_denied_handler switch_user: false login_throttling: ~ contao_login: remember_me: true remember_me: secret: '%kernel.secret%' remember_me_parameter: autologin token_provider: doctrine: true logout: path: contao_frontend_logout access_control: - { path: ^%contao.backend.route_prefix%/login$, roles: PUBLIC_ACCESS } - { path: ^%contao.backend.route_prefix%/logout$, roles: PUBLIC_ACCESS } - { path: ^%contao.backend.route_prefix%(/|$), roles: ROLE_USER } - { path: ^/, roles: [PUBLIC_ACCESS] } ``` The Contao core-bundle is now installed and activated. Use the `contao:migrate` command to upgrade the database and the `contao:user:create` command to create your first back end user.
