Prefab installation of Yii 2 extensions
The preferred way to install this extension is through composer.
Either run
php composer.phar require --prefer-dist schmunk42/yii2-playground "*"
or add
"schmunk42/yii2-playground": "*"
to the require section of your composer.json file.
Once the extension is installed, simply open the module default controller, eg. http://localhost/app/web/index.php?r=playground
All modules, components, widgets, etc... are registered automatically if needed in the module's Bootstrap::bootstrap() method.
