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!

Hi! Thank you but I still don't understand how to write my own butler commands

I would also love to know how to do this.

The instruction above does not work for me, I cannot find the "Print variables" option in the automation options.

Riley, can you please add a screen shot of the working Automation rule you set up for this?
