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:

def foo bar
  return bar
end

var getCityTemperature = function(city) {
  console.log(city)
  var url = "http://api.openweathermap.org/data/2.5/weather?q=" + city + "&APPID=b3e354ab2227f3e98542190461b7fe44&units=metric"
  var response = $.get(url).done(function() {
    $('#cityWeather').html("Current temperature: " + response.responseJSON.main.temp + "&#x2103")
  })
}

This is Ruby:

def print_hi(name)
  puts "Hi, #{name}"
end

print_hi('Tom')
#=> prints 'Hi, Tom' to STDOUT.

def foo bar
  puts bar
end

This is javascript

var getCityTemperature = function(city) {
  console.log(city)
  var url = "http://api.openweathermap.org/data/2.5/weather?q=" + city + "&APPID=b3e354ab2227f3e98542190461b7fe44&units=metric"
  var response = $.get(url).done(function() {
    $('#cityWeather').html("Current temperature: " + response.responseJSON.main.temp + "&#x2103")
  })

}
