+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.[^2]
+
+Jekyll requires blog post files to be named according to the following format[^1]:
+
+`YEAR-MONTH-DAY-title.MARKUP`
+
+Where `YEAR` is a four-digit number, `MONTH` and `DAY` are both two-digit numbers, and `MARKUP` is the file extension representing the format used in the file. After that, include 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[^2]:
+
+{% highlight ruby %}
+def print_hi(name)
+  puts "Hi, #{name}"
+end
+print_hi('Tom')
+#=> prints 'Hi, Tom' to STDOUT.
+
+# There's 80 cols necessary to be supported in the template, otherwise I'll str
+# uggle.
+{% endhighlight %}
+

+[^2]: There's `--livereload` flag that's also cool to use. But I think I'm not ready to look into that just yet. And it should be even longer because why not. We want to wrap, and BAD.
