Try to use github pages and jekyll

Just now, I’m trying to use github pages and jekyll.

It’s great that we are able to host web pages without any paid server (Although only static files).

It’s cool that we are able to build blog contents without any independent database.

Like gihub flavored markdown, if you write a code such as following:

```clojure
(->> (range 0 10 2)
  (map #(* % 10))
  (reduce + ))
;=> 200
```

The syntax is highlited such as following:

(->> (range 0 10 2)
  (map #(* % 10))
  (reduce + ))
;=> 200
