You’ll find this post in your _posts directory - edit this post and re-build (or run with the -w switch) to see your changes! To add new posts, simply add a file in the _posts directory that follows the convention: YYYY-MM-DD-name-of-post.ext.

Jekyll also offers powerful support for code snippets:

package main

import "fmt"

func main() {
    fmt.Println("こんにちわ世界")
}
