With this script you can check the Contao Open Source CMS system requirements, validate an existing Contao installation or set up a new Contao installation.

Here is a short overview of what you can do with the script:

• Check which Contao versions can be installed;
• check if PHP is allowed to write files on the server;
• check if the Live Update service can be used;
• check if the Composer package manager can be used;
• check if the extension repository can be used;
• install the latest Contao version or Contao LTS version;
• validate an existing Contao installation.

Upload the /check folder to your server where you want to install Contao. To validate an existing installation, upload the /check folder to the root of your Contao installation. Then open it in a web browser.

The web installer requires the PHP extensions "curl" and "Zip" to be installed in order to download and extract the latest Contao release.
