21<h2>Getting the Gist of Markdown's Formatting Syntax</h2>
22<p>This page offers a brief overview of what it's like to use
23Markdown. The <a href="/projects/markdown/syntax" title=
24"Markdown Syntax">syntax page</a> provides complete, detailed
25documentation for every feature, but Markdown should be very easy
26to pick up simply by looking at a few examples of it in action. The
27examples on this page are written in a before/after style, showing
28example syntax and the HTML output produced by Markdown.</p>
29<p>It's also helpful to simply try Markdown out; the <a href=
30"/projects/markdown/dingus" title="Markdown Dingus">Dingus</a> is a
31web application that allows you type your own Markdown-formatted
32text and translate it to XHTML.</p>
33<p><strong>Note:</strong> This document is itself written using
34Markdown; you can <a href="/projects/markdown/basics.text">see the
35source for it by adding '.text' to the URL</a>.</p>
36<h2>Paragraphs, Headers, Blockquotes</h2>
37<p>A paragraph is simply one or more consecutive lines of text,
38separated by one or more blank lines. (A blank line is any line
39that looks like a blank line -- a line containing nothing spaces or
40tabs is considered blank.) Normal paragraphs should not be intended
41with spaces or tabs.</p>
42<p>Markdown offers two styles of headers: <em>Setext</em> and
43<em>atx</em>. Setext-style headers for <code>&lt;h1&gt;</code> and
44<code>&lt;h2&gt;</code> are created by "underlining" with equal
45signs (<code>=</code>) and hyphens (<code>-</code>), respectively.
46To create an atx-style header, you put 1-6 hash marks
47(<code>#</code>) at the beginning of the line -- the number of
48hashes equals the resulting HTML header level.</p>
49<p>Blockquotes are indicated using email-style '<code>&gt;</code>'
50angle brackets.</p>
51<p>Markdown:</p>
52<pre>
53<code>A First Level Header
54====================
55
56A Second Level Header
57---------------------
58
59Now is the time for all good men to come to
60the aid of their country. This is just a
61regular paragraph.
62
63The quick brown fox jumped over the lazy
64dog's back.
65
66### Header 3
67
68&gt; This is a blockquote.
69&gt; 
70&gt; This is the second paragraph in the blockquote.
71&gt;
72&gt; ## This is an H2 in a blockquote
73</code>
74</pre>
75<p>Output:</p>
76<pre>
77<code>&lt;h1&gt;A First Level Header&lt;/h1&gt;
78
79&lt;h2&gt;A Second Level Header&lt;/h2&gt;
80
81&lt;p&gt;Now is the time for all good men to come to
82the aid of their country. This is just a
83regular paragraph.&lt;/p&gt;
84
85&lt;p&gt;The quick brown fox jumped over the lazy
86dog's back.&lt;/p&gt;
87
88&lt;h3&gt;Header 3&lt;/h3&gt;
89
90&lt;blockquote&gt;
91    &lt;p&gt;This is a blockquote.&lt;/p&gt;
92
93    &lt;p&gt;This is the second paragraph in the blockquote.&lt;/p&gt;
94
95    &lt;h2&gt;This is an H2 in a blockquote&lt;/h2&gt;
96&lt;/blockquote&gt;
97</code>
98</pre>
99<h3>Phrase Emphasis</h3>
100<p>Markdown uses asterisks and underscores to indicate spans of
101emphasis.</p>
102<p>Markdown:</p>
103<pre>
104<code>Some of these words *are emphasized*.
105Some of these words _are emphasized also_.
106
107Use two asterisks for **strong emphasis**.
108Or, if you prefer, __use two underscores instead__.
109</code>
110</pre>
111<p>Output:</p>
112<pre>
113<code>&lt;p&gt;Some of these words &lt;em&gt;are emphasized&lt;/em&gt;.
114Some of these words &lt;em&gt;are emphasized also&lt;/em&gt;.&lt;/p&gt;
115
116&lt;p&gt;Use two asterisks for &lt;strong&gt;strong emphasis&lt;/strong&gt;.
117Or, if you prefer, &lt;strong&gt;use two underscores instead&lt;/strong&gt;.&lt;/p&gt;
118</code>
119</pre>
120<h2>Lists</h2>
121<p>Unordered (bulleted) lists use asterisks, pluses, and hyphens
122(<code>*</code>, <code>+</code>, and <code>-</code>) as list
123markers. These three markers are interchangable; this:</p>
124<pre>
125<code>*   Candy.
126*   Gum.
127*   Booze.
128</code>
129</pre>
130<p>this:</p>
131<pre>
132<code>+   Candy.
133+   Gum.
134+   Booze.
135</code>
136</pre>
137<p>and this:</p>
138<pre>
139<code>-   Candy.
140-   Gum.
141-   Booze.
142</code>
143</pre>
144<p>all produce the same output:</p>
145<pre>
146<code>&lt;ul&gt;
147&lt;li&gt;Candy.&lt;/li&gt;
148&lt;li&gt;Gum.&lt;/li&gt;
149&lt;li&gt;Booze.&lt;/li&gt;
150&lt;/ul&gt;
151</code>
152</pre>
153<p>Ordered (numbered) lists use regular numbers, followed by
154periods, as list markers:</p>
155<pre>
156<code>1.  Red
1572.  Green
1583.  Blue
159</code>
160</pre>
161<p>Output:</p>
162<pre>
163<code>&lt;ol&gt;
164&lt;li&gt;Red&lt;/li&gt;
165&lt;li&gt;Green&lt;/li&gt;
166&lt;li&gt;Blue&lt;/li&gt;
167&lt;/ol&gt;
168</code>
169</pre>
170<p>If you put blank lines between items, you'll get
171<code>&lt;p&gt;</code> tags for the list item text. You can create
172multi-paragraph list items by indenting the paragraphs by 4 spaces
173or 1 tab:</p>
174<pre>
175<code>*   A list item.
176
177    With multiple paragraphs.
178
179*   Another item in the list.
180</code>
181</pre>
182<p>Output:</p>
183<pre>
184<code>&lt;ul&gt;
185&lt;li&gt;&lt;p&gt;A list item.&lt;/p&gt;
186&lt;p&gt;With multiple paragraphs.&lt;/p&gt;&lt;/li&gt;
187&lt;li&gt;&lt;p&gt;Another item in the list.&lt;/p&gt;&lt;/li&gt;
188&lt;/ul&gt;
189</code>
190</pre>
191<h3>Links</h3>
192<p>Markdown supports two styles for creating links: <em>inline</em>
193and <em>reference</em>. With both styles, you use square brackets
194to delimit the text you want to turn into a link.</p>
195<p>Inline-style links use parentheses immediately after the link
196text. For example:</p>
197<pre>
198<code>This is an [example link](http://example.com/).
199</code>
200</pre>
201<p>Output:</p>
202<pre>
203<code>&lt;p&gt;This is an &lt;a href="http://example.com/"&gt;
204example link&lt;/a&gt;.&lt;/p&gt;
205</code>
206</pre>
207<p>Optionally, you may include a title attribute in the
208parentheses:</p>
209<pre>
210<code>This is an [example link](http://example.com/ "With a Title").
211</code>
212</pre>
213<p>Output:</p>
214<pre>
215<code>&lt;p&gt;This is an &lt;a href="http://example.com/" title="With a Title"&gt;
216example link&lt;/a&gt;.&lt;/p&gt;
217</code>
218</pre>
219<p>Reference-style links allow you to refer to your links by names,
220which you define elsewhere in your document:</p>
221<pre>
222<code>I get 10 times more traffic from [Google][1] than from
223[Yahoo][2] or [MSN][3].
224
225[1]: http://google.com/        "Google"
226[2]: http://search.yahoo.com/  "Yahoo Search"
227[3]: http://search.msn.com/    "MSN Search"
228</code>
229</pre>
230<p>Output:</p>
231<pre>
232<code>&lt;p&gt;I get 10 times more traffic from &lt;a href="http://google.com/"
233title="Google"&gt;Google&lt;/a&gt; than from &lt;a href="http://search.yahoo.com/"
234title="Yahoo Search"&gt;Yahoo&lt;/a&gt; or &lt;a href="http://search.msn.com/"
235title="MSN Search"&gt;MSN&lt;/a&gt;.&lt;/p&gt;
236</code>
237</pre>
238<p>The title attribute is optional. Link names may contain letters,
239numbers and spaces, but are <em>not</em> case sensitive:</p>
240<pre>
241<code>I start my morning with a cup of coffee and
242[The New York Times][NY Times].
243
244[ny times]: http://www.nytimes.com/
245</code>
246</pre>
247<p>Output:</p>
248<pre>
249<code>&lt;p&gt;I start my morning with a cup of coffee and
250&lt;a href="http://www.nytimes.com/"&gt;The New York Times&lt;/a&gt;.&lt;/p&gt;
251</code>
252</pre>
253<h3>Images</h3>
254<p>Image syntax is very much like link syntax.</p>
255<p>Inline (titles are optional):</p>
256<pre>
257<code>![alt text](/path/to/img.jpg "Title")
258</code>
259</pre>
260<p>Reference-style:</p>
261<pre>
262<code>![alt text][id]
263
264[id]: /path/to/img.jpg "Title"
265</code>
266</pre>
267<p>Both of the above examples produce the same output:</p>
268<pre>
269<code>&lt;img src="/path/to/img.jpg" alt="alt text" title="Title" /&gt;
270</code>
271</pre>
272<h3>Code</h3>
273<p>In a regular paragraph, you can create code span by wrapping
274text in backtick quotes. Any ampersands (<code>&amp;</code>) and
275angle brackets (<code>&lt;</code> or <code>&gt;</code>) will
276automatically be translated into HTML entities. This makes it easy
277to use Markdown to write about HTML example code:</p>
278<pre>
279<code>I strongly recommend against using any `&lt;blink&gt;` tags.
280
281I wish SmartyPants used named entities like `&amp;mdash;`
282instead of decimal-encoded entites like `&amp;#8212;`.
283</code>
284</pre>
285<p>Output:</p>
286<pre>
287<code>&lt;p&gt;I strongly recommend against using any
288&lt;code&gt;&amp;lt;blink&amp;gt;&lt;/code&gt; tags.&lt;/p&gt;
289
290&lt;p&gt;I wish SmartyPants used named entities like
291&lt;code&gt;&amp;amp;mdash;&lt;/code&gt; instead of decimal-encoded
292entites like &lt;code&gt;&amp;amp;#8212;&lt;/code&gt;.&lt;/p&gt;
293</code>
294</pre>
295<p>To specify an entire block of pre-formatted code, indent every
296line of the block by 4 spaces or 1 tab. Just like with code spans,
297<code>&amp;</code>, <code>&lt;</code>, and <code>&gt;</code>
298characters will be escaped automatically.</p>
299<p>Markdown:</p>
300<pre>
301<code>If you want your page to validate under XHTML 1.0 Strict,
302you've got to put paragraph tags in your blockquotes:
303
304    &lt;blockquote&gt;

306    &lt;/blockquote&gt;
307</code>
