Its good to see that Drupal 8 has being used namespaces, Object oriented and weird directory structure.
Alex Bronstein long time core developer and first time on blogger said has written an excellence piece offering a small introduction to change to Drupal 8 or people who are less.
I am blogging site. Originally I hail from the village name Tundri, located in Chamoli district of Uttarakhand.
That's why I am called Tundriyal (The guy from Tundri Village)
The village is 3-4 KM far from the road and 30+ families are leaving. So this is the very peaceful place and best for spending your summer season as a picnic.
