Hi,
Welcome to Org mode community.
You will need to add your org file to agenda_files (org->file list for
agenda->add/move current file...).
If you want to learn more about basic concepts, it may be also a good
idea to watch Rainer König's org mode tutorial series
(https://www.youtube.com/watch?
I know this is basic but I am having difficulty getting TODO states to work. In
ORG I select new heading than TODO from the menu but I don’t understand how to
save this so that it works with things like agenda view?
