-Jekyll requires blog post files to be named according to the following format:
+`avec un peu de code`
+et *de l'italique*
 
-`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:
-
-{% highlight ruby %}
-def print_hi(name)
-  puts "Hi, #{name}"
-end
-print_hi('Tom')
-#=> prints 'Hi, Tom' to STDOUT.
-{% endhighlight %}
