Add a small tutorial

[fwsmit]

After creating a task it's not entirely clear how to mark it as avoided or done. I figured it out now, but a small tutorial or text in the description of the app would be helpful.

Hey, that is a great idea. May you propose something?

Hi @CrazyMarvin I’d like to work on the documentation 😅

[CrazyMarvin]

That would be awesome, @LuluNwenyi! 😃 Please let me know if you will come upon any questions. Thank you very much.

@LuluNwenyi, are you still up for this task? @fwsmit, may you propose a little text for the tutorial which would have made the use of To Don't more comfortable for you?

I'm sorry, I don't actively use the app anymore. The interface is already clearer IIRC.
