If you haven't already, you need to install the phpqt extension.
At first run composer install
to install dev dependencies and to create the autoloader. After that you can simply start the project by running php start.php DemoName
where DemoName is a folder in the examples
directory. Currently, there are two demos, so you can run them by,
php start.php Authentication
# OR
php start.php Downloader
The downloader demo cannot handle downloading multiple files at the same time. It crashes with some error that I don't yet understand what those are.
