+Markdown Extra
+--------------
+
+**StackEdit** supports **Markdown Extra**, which extends **Markdown** syntax with some nice features.
+
+
+### Tables
+
+**Markdown Extra** has a special syntax for tables:
+
+Item      | Value
+--------- | -----
+Computer  | $1600
+Phone     | $12
+Pipe      | $1
+
+You can specify column alignment with one or two colons:
+
+| Item      | Value | Qty  |
+| :-------- | -----:| :--: |
+| Computer  | $1600 |  5   |
+| Phone     |   $12 |  12  |
+| Pipe      |    $1 | 234  |
+
+
+### Definition Lists
+
+**Markdown Extra** has a special syntax for definition lists too:
+
+Term 1
+Term 2
+:   Definition A
+:   Definition B
+
+Term 3
+
+:   Definition C
+
+:   Definition D
+
+	> part of definition D
+
+
+### Fenced code blocks
+
+**GitHub**'s fenced code blocks are also supported with **Prettify** syntax highlighting:
+
+```
+// Foo
+var bar = 0;
+```
+
+
+### Special Attributes
+
+With **Markdown Extra**, you can specify `class` and `id` attributes on headers and fenced code blocks just like this:
+
+##### Title example {#my-title}
+
+``` {#my-id .my-class}
+var foo = bar;
+```
+
+Then you can create cross-references like this: [beginning of the document](#welcome).
+
+
+> **NOTE:** You can find more information about **Markdown** syntax [here][1] or about **Markdown Extra** [here][2].
