It would be great if a vault or a part of the vault could be easily published on the web. This could potentially be very simple through e.g. GitHub Pages, which has templating mechanisms that turn markdown into HTML (https://pages.github.com/).
Unfortunately, my first test of doing this with the current markdown generated by Obsidian failed:
The link is broken and the image is not shown. I assume this is because of a mismatch in markdown syntax between Obsidian and GitHub pages; also GitHub pages cannot know the Obsidian setting for the folder in which file attachments are located.
It would be great to have a tutorial, export script or other helpful material for turning Obsidian content into web pages!
