@hieu - Iām very much not a developer, myselfā¦
Are you looking for help with Git/Github, or are you familiar with that part of the process? Thereās a lot to unpack there, so Iād rather know your level of comfort before I walk through the process.
For the Obsidian part, I go to settings and set the āNew link formatā to āAbsolute path in vaultā *Disclaimer - some folks donāt like this as much, because the link format is not as clean as wikilinks. It is a standard link format, though, and works across platforms very well.
Then, using the Github app on Android, I can open the repository and navigate the files. The links work in the app like they do in Obsidian. This is the āview-onlyā interface I mentioned.
I donāt do much editing on mobile, mostly because itās messy. Iāve edited straight through the Gihub app, and I have Markor installed - it will also work in a pinch. I could not get Git journal to do what I wanted.
Good luck!
