Automatic download and installation
In the administration area of your Contao website you can find the "Extension catalog" module, which allows you to browse the extension list and to install extensions at the push of a button. Use the filter and sorting options to find a particular extension and click the info icon or extension title to open the details page and install the module.
Insert "zad_switcher" in the search box to find the extension. When you push the install button, Contao will automatically download and install the extension and update the database if necessary.
After installation, the "Extension manager" module allows you to update or uninstall the extension. It automatically checks for updates and notifies you if a new version is available.
Manual download and installation
You can download the last version of the module directly from the following links:
Uncompress the files and copy them to your Contao installation, inside the directory "system/modules/zad_switcher". Then, enter into the administration area of your Contao website, go to the "Extension manager" module and push the "Update database" button.
Follow the same steps for upgrading to a new version.
