This introductory course is intended to cover the basics of Butler for Trello.
When I created this course, the ButlerBot was the main tool to use for creating workflows in Trello boards. This has changed.
Today, the Butler Power-Up is the only tool that is recommended for use if you want to implement some workflows into your Trello boards.
This free course covers only the ButlerBot - and still gives you some good insights into how the tool is working. This hasn't changed with the Power-Up. However, the Butler Power-Up's user interface looks different than than the ButlerBot.
However, if you want to learn how to set up meaningful workflows in your Trello boards with the Butler Power-Up, I recommend you check out the workshop course I am offering on my website.
