The source project of this merge request has been removed.

Katrin Leinweber (GTLB) requested to merge (removed):patch-9988 into master Mar 10, 2019

The 1st slides says that the deck is depreciated ;-)

Since neither https://about.gitlab.com/training/ nor https://gitlab-training.gitlab.io/ are linked on the page at all, should either or both maybe be mentioned on this page?
