Paragraphs

Don\'t indent paragraphs
Words wrap and fill as needed
Use blank lines as separators
Four or more minus signs make a horizontal rule
%%% or \\\\ makes a linebreak (in headings and lists too)

Lists

asterisk for first level

asterisk-asterisk for second level, etc.

Use * for bullet lists, # for numbered lists (mix at will)
semicolon-term-colon-definition for definition lists:

term here
definition here, as in the <DL><DT><DD> list

One line for each item

Headings

= at the start of a line makes a large heading
== at the start of a line makes a medium heading
=== at the start of a line makes a small heading

Emphasis

Use doubled undercores (__) for underlined text (not recommended)
Use doubled slashes (//) for emphasis
Use doubled stars (**) for strong emphasis
Mix them at will: very strong emphasis
Emphasis can be used multiple times within a line, but cannot cross line boundaries:
//this

will not work//

References}
Hyperlinks to other pages within the Wiki are made by placing the page name in square brackets: [this is a page link]

Hyperlinks to external pages are done like this: [http://www.example.com]

You can name the links by providing the hyperlink and then a name:
[http://phpwiki.sourceforge.net/ PhpWiki home page]

You can create footnotes by using [1], [2], [3], ... like this here ^[1]; see footnote for counterpart

Also, the old way of linking URLs is still supported: precede URLs with "http:", "ftp:" or "mailto:" to create links automatically as in: http://example.com/

URLs ending with .png, .gif, or .jpg are inlined as images if in square brackets, by themselves

HTML Mark-Up Language

HTML will display as-is

< and > are themselves

Entities (e.g. &) will not convert to characters

Table is supported

Start and end the line with a single-bar (|) to create a table

One line per row, do not insert blank line, or the table ends

Single-bar separates table (<td></td>) cells

Don\'t end a line with single or double bar; otherwise, a blank cell results

Example:

| Column 1 | Column 2 | | Cell a1 | Cell a2 | | Cell b1 | Cell b2 |
Result:

Cell a1 Cell a2

Cell b1 Cell b2

More detail than you want to know

Footnotes:

[1] You can define footnote text by starting the line with [n], like here.
