+## Macros
+
+Macros extend authoring options with computed values evaluated at display time.
+There are two types: *inline*, which can be used in the middle of a line of
+markdown, and *block*, which enclose a series of lines.
+
+### Inline Macros
+
+The basic format of an inline macro is:
+
+`{{NAME [KEYWORD ..] [PARAM="VALUE" ..]}}`
+
+* `NAME` is the name of the macro. It is always lower case.
+* `KEYWORD` is a bare word
+* `PARAM` is a parameter name
+* `VALUE` is the value of the associated parameter
+
+No macro requires keywords or parameters, but some support them; they are documented below.
+
+### Block Macros
+
+The format of a block macro uses the same format for name, keywords and parameters. The closing
+braces must appear on their own line, and both the opening and closing lines must be
+surrounded by blank lines. This ensures the block macro is not interpreted as markdown.
+
+```
+Before the macro..
+
+{{NAME [KEYWORD ..] [PARAM="VALUE" ..]
+
+..inside the macro..
+
+}}
+
+..after the macro.
+```
+
+### Supported Macros
+
+This section documents all supported macros.
+
+WIP (move to its own page)
+
+{{style striped equal-widths
+
+| Type | To Get | Description |
+|------|--------|-------------|
+|{{{ <pre>{{user}}</pre> }}} | {{user}} | A hyperlink to the current user's wiki page. |
+|{{{ <pre>{{style [STYLE ..]<br>pretty markup goes here!<br><br>}}</pre> }}}| pretty markup goes here! | Styled markup. See Block Styling and Positioning, below. |
+|{{{ <pre>{{toc [STYLE ..] depth="N"}}</pre>}}} | {{toc depth="1"}} | A table of contents. The default depth is 3, and styles may be assigned as with the `style` macro. |
+|{{{ <pre>{{widget NAME}}</pre> }}} | *varies* | Insert specified widget; see [Wiki Syntax: Widgets](/Widgets). |
+
+
+### Block Styling and Positioning
+
+Several styles are supported by the editor, which may be freely combined. These include:
+
+* **box**: block element with background and border
+* **full-width**: Expand block to fill all horizontal space
+* **right**: right-aligned floating block (maximum 30% of full width)
+* **left**: left-aligned floating block (maximum 30% of full width)
+* **center**: centered block
+* **inline**: contained within the current text line

+
+### Tables
+
+Basic tables follow the Github-Flavoured Markdown. By default, table cells may not contain newlines, but you can add multi-line content to your tables using {{{ &#123;&#123;&#123; and &#125;&#125;&#125; }}}:
+
+{{style equal-widths striped
+
+| Type | To Get |
+|------|--------|
+| {{{
+
+<pre>
+\\| head 1 \\| head 2 \\|
+\\| ------ \\| ------ \\|
+\\| cell 1 \\| cell 2 \\|
+</pre>
+
+}}} | {{{ <table><tr><th>head 1</th><th>head 2</th></tr><tr><td>cell 1</td><td>cell 2</td></tr></table> }}} |
+| {{{
+
+<pre>
+\\| head 1 \\| head 2 \\|
+\\| ------ \\| ------ \\|
+\\| \\&#123;\\&#123;\\&#123;
+
+multi-line
+content
+
+&#125;&#125;&#125; \\| cell 3 \\|
+</pre>
+
+}}} | {{{ <table><tr><th>head 1</th><th>head 2</th></tr><tr><td><p>multi-line<br>content</p></td><td>cell 3</td></tr></table> }}} |
+
+}}
+
+
+#### Table Styling
+
+{{style box right outer
+
+**Striped, Equal-Widths Example:**
+
+{{style striped equal-widths inner1
+
+| A | B|
+|---|--|
+| This table has | and |
+| equal | alternating |
+| widths! | backgrounds! |
+
+}}
+
+
+**Layout Example:**
+
+{{style layout inner2
+
+| A | B|
+|---|--|
+| row 1, col 1 | row 1, col 2|
+| row 2, col 1 | row 2, col 2|
+
+}}
+
+}}
+
+
+By wrapping a table in a `style` macro, you can use the following block-level styles on the tables themselves:
+
+* `striped`: Apply zebra-striping to table rows
+* `equal-widths`: Enforce equal widths of all table columns
+* `layout`: Hide the table headers, borders, and background colors. This is useful in cases
+            where you would like to control layout of elements using tables.
