Zero-to-Emacs-and-Org-roam VS org-remark

Alternatively, I have had success with this way https://github.com/nobiot/Zero-to-Emacs-and-Org-roam/blob/v1/100.pdf-tools-org-noter.md

Have you seen this? https://github.com/nobiot/Zero-to-Emacs-and-Org-roam It's still a work-in-progress but it may be along the lines of what you're looking for.

Personally, I wouldn't recommend setting up org-roam at first. It's excellent, but it's just going to be too daunting for a beginner when combined with all the other things. I'd start by just learning emacs and org-mode. Core org-mode has enough functionality built-in to start building knowledgebases, and the org-mode manual is excellent. You can add-in org-roam later. (And you might find that org-roam is overkill and something like howm mode to get backlinks is enough.) The beauty of emacs is that you can move your notes from one system to another easily.

I'm new to org-roam and trying to use v2 directly. My process is currently looking at the excellent manual (https://www.orgroam.com/manual.html) and intro (https://github.com/nobiot/Zero-to-Emacs-and-Org-roam) for v1 and trying to map these to v2. But as I managed to install org-roam and emacsql-sqlite3 in Android/Termux just yesterday evening, I can't say if it's useable enough.

For Windows, I have done this. So far, it works really well

My primary goal is to keep notes organized, portable and "connected" using Emacs, so focus is still on it and in few days I think I will have my favorite setup using Emacs + Org + roam. In the process I discovered Zero-to-Emacs-and-Org-roam - kudos to the creator - really helped me.

I use something similar, called org-remark. By the description of both, they seem to share functionalities. Just mentioning it for visibility :)

org-remark hits some of your requests, but I think lacks the git parts in point 3.

https://github.com/nobiot/org-remark might also work

There is also Org-remark, which lets you highlight and annotate any text file using Org-mode.

Also if you're annotating plain text, org-remark is great. I love not having to use the mouse to select text.

What happens when line number changes? For example https://github.com/nobiot/org-remark handles this changes, but can only anotate org-mode files

Org-Remark, for plain text files perhaps.
