maybe dummy issue: can't show posts in _post?

[neilengineer]

I've successfully installed the theme, index.md rendered into _site/index.html and was shown locally perfectly. But if I add new post in _post/ dir that I created, I didn't see the new post show up?
I think the _post/ folder's not parsed when building?

I've used other theme, which can show same post.
