Welcome! This is a great tool and community 😀 . What I would suggest is creating a "biology" and "computing" hierarchy to start. So what I would do is create 2 files: - biology.2022.09.02 - computing.2022.09.02 By creating these 2 files you'll now have a hierarchy for both. Take your notes as you need to in the respective files. Then the next day you could easily create the file for that day, just increase the number "02" to "03" or whatever. That would be to start. I like to hear others' thoughts on this too and correct any mistakes I may have made. 😉
