Review the "Drupal Core Ladder" at website above and finish it for Drupal 8.  It is important to note any issues as Drupal 8 is not out yet and you will be one of the first users climbing the ladder for Drupal 8 core. If you find any issues, document while providing feedback on how to resolve.

Deliverables: Provide evidence for completing the ladders by writing a blog post with screenshots and notes about the experience. What did you learn? How will you continue to utilize these skills?
