> composer require viewi/viewi:dev-master
> vendor/bin/viewi new
This will generate for you the Starter application with some demo components. Also it will insert the default code for using Viewi as a standalone application into your /index.php or /public/index.php. If it didn't happen for some reason just go and include this code by yourself:
include __DIR__ . '/viewi-app/viewi.php'; Viewi\App::handle();
Depending on the folder structure of your application, Viewi components will be located in one of these folders:
viewi-app/ or src/ViewiApp/
Also make sure you didn't forget about the autoload: require __DIR__ . '/vendor/autoload.php';
After that just run your server or use a built in PHP development server:
> php -S localhost:8000
and open your browser at http://localhost:8000/. If everything was done correctly you should be able to see the Starter application.
