How to create a blog without BSS

I am considering using Publii to publish my blog alongside a website hosted by BSS Sites.

How can I SFTP blog files to website hosted by BSS? I assume I need to create an A record in Cloudflare DNS page for the domain ftp.mywebsite.com?

Has anyone else implemented this solution?

I haven’t used Publii myself, but since it is a static site generator, this means that you will have to publish your blog to a subdomain like blog.example.com. The built-in Bootstrap Studio Sites hosting doesn’t allow direct file access, you can only publish to it from Bootstrap Studio. You can host your blog on any standard hosting provider or free services like Cloudflare Pages and GitHub Pages and setup a subdomain for them. I would expect that Publii has documentation on how to set this up.

Thank you Martin for the comments.
