User-Manual

Is your feature request related to a problem? Please describe.

The app being rather intransparent about its features and how to use them.

Describe the solution you'd like

I'm missing a user-manual on how to use the app.
My original problem is that I would like to specify the duration of tasks when creating them. At the moment I do this by creating the task without any specifics, then edit it to add duration, start time, priority etc. I guess there is a way to already do this in the "new task"-prompt with some code (Maybe this assumption is wrong, then I would strongly request this feature), but I just don't find any explanation, neither on the nextcloud-homepage nor here.
So for me as a dumb user without any background in administration, development, whatsoever, it would be great to have an simple manual on how to use the app. Maybe there even is one out there; then it should be placed more prominent. Because even if I am a little dumb, I still would imagine that there are a lot more similarily dumb people out there.
(In my opinion, usability is something nextcloud lacks in general, but that's a different discussion).

Additional context

No response

The issue names no files, tests, or entry points. Begin by locating the app's existing user-facing documentation and the new-task prompt, then determine where a manual should be maintained and surfaced. Done means documenting task creation fields such as duration, start time, and priority, with the manual placed prominently for users.
