This page is distributed via Vercel, and the repository uses Git. Posts are written using Markdown files, and the structure is such that postdata receives those files, postdetail renders the detail page, and posts displays the list of posts. I thought there wouldn't be a way to post without the local project files, so I considered just going with the easier option of using a CMS, but wait, isn't the post updated just by adding files and committing via the GitHub app or a mobile web browser...? So, does it work well?
