+## Lists
+
+Unordered
+
++ Create a list by starting a line with `+`, `-`, or `*`
++ Sub-lists are made by indenting 2 spaces:
+    - Marker character change forces new list start:
+        * Ac tristique libero volutpat at
+        + Facilisis in pretium nisl aliquet
+        - Nulla volutpat aliquam velit
++ Very easy!
+
+Ordered
+
+1. Lorem ipsum dolor sit amet
+2. Consectetur adipiscing elit
+3. Integer molestie lorem at massa
+
+
+1. You can use sequential numbers...
+1. ...or keep all the numbers as `1.`
+
+Start numbering with offset:
+
+57. foo
+1. bar
+
+
+## Code
+
+Inline `code`
+
+Indented code
+
+    // Some comments
+    line 1 of code
+    line 2 of code
+    line 3 of code
+
+
+Block code "fences"
+
+```
+Sample text here...
+```
+
+Syntax highlighting
+
+``` js
+var foo = function (bar) {
+  return bar++;
+};
+
+console.log(foo(5));
+```
