This guide is a very brief overview, with examples, of the syntax that [Markdown] supports. It is itself written in Markdown and you can copy the samples over to the left-hand pane for experimentation. It's shown as *text* and not *rendered HTML*.
First thing is first. You can use *stars* or _underscores_ for italics. **Double stars** and __double underscores__ do bold. ***Three together*** do ___both___.
Paragraphs are pretty easy too. Just have a blank line between chunks of text.
> This chunk of text is in a block quote. Its multiple lines will all be
Sometimes you want to include some code, such as when you are explaining how `<h1>` HTML tags work, or maybe you are a programmer and you are discussing `someMethod()`.
> You can also use preformatted text with your blockquotes
> as long as you add at least five spaces.
Headings
========
There are a couple of ways to make headings. Using three or more equals signs on a line under a heading makes it into an "h1" style. Three or more hyphens under a line makes it "h2" (slightly smaller). You can also use multiple pound symbols before and after a heading. Pounds after the title are ignored. Here's some examples:
This is H1
==========
This is H2
----------
# This is H1
## This is H2
### This is H3 with some extra pounds ###
#### You get the idea ####
##### I don't need extra pounds at the end
###### H6 is the max
Links
=====
Let's link to a few sites. First, let's use the bare URL, like <http://www.github.com>. Great for text, but ugly for HTML.
Next is an inline link to [Google](http://www.google.com). A little nicer.
This is a reference-style link to [Wikipedia] [1].
Lastly, here's a pretty link to [Yahoo]. The reference-style and pretty links both automatically use the links defined below, but they could be defined *anywhere* in the markdown and are removed from the HTML. The names are also case insensitive, so you can use [YaHoO] and have it link properly.
[1]: http://www.wikipedia.org/
[Yahoo]: http://www.yahoo.com/
Title attributes may be added to links by adding text after a link.
This is the [inline link](http://www.bing.com "Bing") with a "Bing" title.
You can also go to [W3C] [2] and maybe visit a [friend].
[2]: http://w3c.org (The W3C puts out specs for web-based things)
[Friend]: http://facebook.com/ "Facebook!"
Email addresses in plain text are not linked: test@example.com.
Email addresses wrapped in angle brackets are linked: <test@example.com>.
They are also obfuscated so that email harvesting spam robots hopefully won't get them.
Lists
=====
* This is a bulleted list
* Great for shopping lists
- You can also use hyphens
+ Or plus symbols
The above is an "unordered" list. Now, on for a bit of order.
1. Numbered lists are also easy
2. Just start with a number
3738762. However, the actual number doesn't matter when converted to HTML.
1. This will still show up as 4.
You might want a few advanced lists:
- This top-level list is wrapped in paragraph tags
- This generates an extra space between each top-level item.
- You do it by adding a blank line
- This nested list also has blank lines between the list items.
- How to create nested lists
1. Start your regular list
2. Indent nested lists with four spaces
3. Further nesting means you should indent with four more spaces
* This line is indented with eight spaces.
- List items can be quite lengthy. You can keep typing and either continue
If you need a horizontal rule you just need to put at least three hyphens, asterisks, or underscores on a line by themselves. You can also even put spaces between the characters.
Those three all produced horizontal lines. Keep in mind that three hyphens under any text turns that text into a heading, so add a blank line if you use hyphens.
If markdown is too limiting, you can just insert your own <strike>crazy</strike> HTML. Span-level HTML <u>can *still* use markdown</u>. Block level elements must be separated from text by a blank line and must not have any spaces before the opening and closing HTML.
