New blog post at the Sevaa blog: https://blog.sevaa.com/build-drupal-8-bootstrap-subtheme-sass/ based on the original Drupal 7 version by Roland Michael dela Peña (arpeggio): https://www.webfoobar.com/node/9 . I’m actually taking his article and turning it into two, dividing the SASS implementation and the Grunt automation into separate pieces.
There’s some good Drupal 8 getting-started guides out there and I’m hoping to add mine to the pile. The better the docs, the better the visibility, the more potent the community.
