We've made it as simple as we can to get started, you just need access to a shell, and run a few commands.
$ composer create-project pbbg-io/titan -s dev$ cd titan$ php artisan titan:install$ php artisan titan:resources$ yarn && yarn run production
Those just creates a new project and runs the installer and publish some assets. On the installer you will be asked some question to setup your database and such. To serve the app you can use the built in webserver
php artisan serve
And there you are. All done
If for some reason that you haven't got a super user, register on your site at http://yoururl.local/register then use the following command
php artisan titan:super-user
You will be asked what account to give it to, generally it's ID 1.
