You’ll find this post in your _posts directory. Go ahead and edit it and re-build the site to see your changes. You can rebuild the site in many different ways, but the most common way is to run jekyll serve, which launches a web server and auto-regenerates your site when a file is updated.

To add new posts, simply add a file in the _posts directory that follows the convention YYYY-MM-DD-name-of-post.ext and includes the necessary front matter. Take a look at the source for this post to get an idea about how it works.

Jekyll also offers powerful support for code snippets:

Clojure

(deftest verify-immutability
  (let [hello (apply array-set "hello")]
    (is (= (apply array-set "hello")
           (into (reduce disj hello "hello") "hello")))
    (is (= (apply array-set "hello") hello))))

Kotlin

fun main(args: Array<String>) {
   if (args.size() == 0) {
      println("Provide a name")
      return
   }
   println("Hello, ${args[0]}!")
}

Javascript

(function(){
  const ONE = 1
  [1,2,3,4,1,2,3,4].map(i => ONE+i);
}());

SQL

SELCET 
  *
FROM Table
LIMIT 1
