[Best practices] Missing installation instructions for sample blog application

[darko-mijic]

Book quotes: "Please refer to the last chapter of this guide to find more details about this
application and the instructions to install it." but there is no section with link to sample blog application.

Thank you for reporting this @eBizHr. You're right. This is indeed missing.

If anyone knows where can that application be downloaded please do tell.
I can't wait to see it. :)

The application is still not public, we're working on it. However, you should expect a small and extremely simple application once it's released.

Meanwhile, if you want to check out a Symfony application developed using these best practices, check out this repo: https://github.com/sensiolabs/dx.symfony.com

The demo application is now available and the docs have been updated by #5164, so this issue is now closed.
