Contao is an Open Source PHP Content Management System for people who want a professional website that is easy to maintain. Visit the project website for more information.

Contao 4 has been designed as a Symfony 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 standard edition as basis for your application.

Edit your composer.json file and add the following requirement:

"require": {
    "contao/core-bundle": "~4.0"
}

Edit your app/config/config.yml file and add the following:

# Contao configuration
contao:
    # Required parameters
    prepend_locale: true
    encryption_key: "%kernel.secret%"

    # Optional parameters
    url_suffix:           .html
    upload_path:          files
    csrf_token_name:      contao_csrf_token
    pretty_error_screens: true
    error_level:          8183 # E_ALL & ~E_NOTICE & ~E_DEPRECATED & ~E_USER_DEPRECATED

Add the Contao routes to your app/config/routing.yml file:

ContaoCoreBundle:
    resource: "@ContaoCoreBundle/Resources/config/routing.yml"

Add the following entries to your app/config/security.yml file:

imports:
    - { resource: "@ContaoCoreBundle/Resources/config/security.yml" }

There is a meta package at contao/contao, which you can require in your composer.json to install all the default bundles at once:

"require": {
    "contao/contao": "~4.0"
}

This is the same as:

"require": {
    "contao/calendar-bundle": "~4.0",
    "contao/comments-bundle": "~4.0",
    "contao/core-bundle": "~4.0",
    "contao/faq-bundle": "~4.0",
    "contao/listing-bundle": "~4.0",
    "contao/news-bundle": "~4.0",
    "contao/newsletter-bundle": "~4.0"
}
