How to print automation variables

[Jer]

Here it said we can, but I don't know how to do that, also I didn't find how to write my automation text instead of using UI to add it, so each time I follow a tutorial i have to search where is the button to write the text I want. 
Thanks for your help

Hello! To print automation variables in Trello using Butler, you can create a new card in the Butler list named "print variables" and add a rule such as "when a label is added to a card, print variables". You can then see the variables in the Rule Logs after running the command. Regarding writing automation text, you can use Butler commands to input your own automation text instead of using the UI to add it. Hope this helps!
