+These are generated by selecting the `max_related` most recent posts that share at least `min_common_tags` tags with the current post.
+If you do not want to display related posts on a specific post, simply add `related_posts: false` to the front matter of the post.

 This theme supports rendering beautiful math in inline and display modes using [MathJax 3](https://www.mathjax.org/) engine. You just need to surround your math expression with `$$`, like `$$ E = mc^2 $$`. If you leave it inside a paragraph, it will produce an inline expression, just like $$ E = mc^2 $$.
