Drupal 8 theming basics

Session

Since Drupal 8 switched to Twig (from PHPtemplate) and a new config system Drupal themers should learn some new things. However these are good changes and I want to give you a short impression to understand why. 

It is not a long course about creating a full new theme from the grond up. I'll talk about creating a sub-theme and modify the defaults provided by the parent instead.
