+You can write regular [markdown](http://markdowntutorial.com/) 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](http://markdowntutorial.com/) - 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:
+
+| Number | Next number | Previous number |
+| :------ |:--- | :--- |
+| Five | Six | Four |
+| Ten | Eleven | Nine |
+| Seven | Eight | Six |
+| Two | Three | One |

+How about a yummy crepe?
+
+![Crepe](http://s3-media3.fl.yelpcdn.com/bphoto/cQ1Yoa75m2yUFFbY2xwuqw/348s.jpg)
+
+Here's a code chunk:
+
+~~~
+var foo = function(x) {
+  return(x + 5);
+}
+foo(3)
+~~~
+
+And here is the same code with syntax highlighting:
+
+```javascript
+var foo = function(x) {
+  return(x + 5);
+}
+foo(3)
+```
+
+And here is the same code yet again but with line numbers:
+
+{% highlight javascript linenos %}
+var foo = function(x) {
+  return(x + 5);
+}
+foo(3)
+{% endhighlight %}
+
+## Boxes
+You can add notification, warning and error boxes like this:
+
+### Notification
+
+{: .box-note}
+**Note:** This is a notification box.
+
+### Warning
+
+{: .box-warning}
+**Warning:** This is a warning box.
+
+### Error
+
+{: .box-error}
+**Error:** This is a error box.
