Maybe it will be more pleasant for blog readers to have a RSS feed.

@jamesliu96 How do you plan to implement RSS feed? I've no idea yet.

[jamesliu96]

Add an RSS link button for each entry top head banner. This link will direct the user to an RSS feed page. RSS feed is generated by a Go module. I wrote an RSS generator in Go before. I'm now publishing it to GitHub. The Go module (can be in action.go) traverse though the wiki directory and get a list for all publications. Then use the RSS generator to generate the RSS feed page.

what about adding a permalink to the RSS feed such as /feed.xml and response to it?

No problem, that's good.
