Our company (Le Phare) is currently using Metronic to build our own admin component in Symfony. I'm using the assets and twig templates from the Metronic Symfony demo. I was wondering why are the Symfony demo files absent from your repo https://github.com/KeenthemesHub/Metronic? Is there another repository? As we are relying on the demo to build our component, we could contribute back to the Metronic repository.
Please note that the Metronic private Github provides the source code that is distributed via Themeforest zip packages and sour Demos and Starter Kits are available on the Metronic Downloads page where you can download starter kits and demos by entering your purchase code.
At the moment Symfony Starter Kit provides only the assets, views, and index/auth pages integration only. In the near future, we will add CRUD and common pages.
At the moment we do not have private repos for Metronic's starter kits and extra demos since we have overall 100+ instances that we distribute from the Metronic Downloads page.
