H1s are easy in Markdown
========================
## H2
### H3
#### H4
##### H5
###### H6
Paragraphs are separated by a blank line.
2nd paragraph. *Italic*, **bold**, and `monospace`. Itemized lists
look like:
* this one
* that one
* the other one
Emphasis, aka italics, with *asterisks* or _underscores_.
Strong emphasis, aka bold, with **asterisks** or __underscores__.
Strikethrough uses two tildes. ~~Scratch this.~~
```
No language indicated, so no syntax highlighting.
But let's throw in a tag.
```
| Tables | Are | Cool |
| ------------- |:-------------:| -----:|
| col 3 is | right-aligned | $1600 |
| col 2 is | centered | $12 |
| zebra stripes | are neat | $1 |
> Blockquotes are very handy in email to emulate reply text.
> This line is part of the same quote.
Quote break.
> This is a very long line that will still be quoted properly when it wraps. Oh boy let's keep writing to make sure this is long enough to actually wrap for everyone. Oh, you can *put* **Markdown** into a blockquote.

_This is italic text_
~~Strikethrough~~
## Blockquotes
> Blockquotes can also be nested...
>> ...by using additional greater-than signs right next to each other...
> > > ...or with spaces between arrows.
## 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
