Common Usage
0x01 Headings
In Markdown, to define a piece of text as a heading, simply add # in front of the text, followed by a space after #. There are six heading levels in total. To get a lower-level heading, add one more #; each additional # reduces the heading size by one level. As shown:

0x02 Lists
List formatting is very common and can keep your document well organized. In Markdown, simply add - in front of the text; if you want an ordered list, add 1. 2. 3. in front of the text.
Note: Keep one character's space between -, 1., and the text.

0x03 Quotes
If you need to quote a sentence from elsewhere in your document, use the "quote" format.
Add > in front of the quoted text, with one character's space between them.

0x04 Bold and Italic
Bold and italic in Markdown are also very simple:
Enclosing a piece of text with two * is the syntax for bold;
Enclosing a piece of text with one * is the syntax for italic.

0x05 Links and Images
Links: In Markdown, to insert a link, simply use [显示文本](链接地址).
Images: In Markdown, to insert an image, simply use .
Note: The syntax for inserting an image is very similar to that for links, except with an extra ! in front.
