You can write regular markdown here and Jekyll will automatically convert it to a nice webpage. I strongly encourage you to take 5 minutes to learn how to write in markdown - it'll teach you how to transform regular text into bold/italics/headings/tables/etc.

Here is some bold text

Here is a secondary heading

Here's a useless table:

How about a yummy crepe?

Here's a code chunk:

var foo = function(x) {
  return(x + 5);
}
foo(3)

And here is the same code with syntax highlighting:

var foo = function(x) {
  return(x + 5);
}
foo(3)

And here is the same code yet again but with line numbers:

{{< highlight python linenos >}} var foo = function(x) { return(x + 5); } foo(3) {{</ highlight >}}
