After installed: RuntimeException: composer.json is not readable.

Hi,

I installed my Drupal 8 installation with Composer as described here: https://github.com/drupal-composer/drupal-project

The problem with that seems to be that Drupal root is set to "web" which is a folder under the project root where the composer.json is saved. I just want to ask here if someone can clarify if there already was a decision about that "where to save the composer.json" thing?! Maybe the project I mentioned above does it not in the right "Drupal 8" way? It seems to be in that way as the vendor folder is placed in another place as if I download Drupal 8 directly from drupal.org in a zip archive where the vendor folder is saved on the same hierarchical level as core, modules and all the other folders.

Best,
Tobias
