Micro.blog supports several frontmatter fields:
draft(true or false)
While Micro.blog mostly ignores the file structure in the ZIP file, it will notice if some of your Markdown files are in a folder called “drafts” and make those drafts in Micro.blog.
The ZIP file cannot be larger than 45 MB.
Do not include any photos in the ZIP file. Micro.blog will look for
img tags (or Markdown image references) and attempt to download those images to store with your Micro.blog-hosted blog. Make sure to add your domain name when importing if the image references do not use absolute URLs.
