In this post you recently made, presumably in response to my question here, I had previously assumed Micro.blog was based on Hugo, but whenever I searched things on Hugo forums and applied it here, I was told yes, but Micro.blog does it differently. Maybe things have changed now, but I searched through the archives at Micro.blog Help first and found one of your posts asking about the differences.

Anyway, I’m mostly stumbling through and finding out things by trial-n-error. The ChatGPT link helped. Thanks!
