+### Brew Variable Syntax
+
+You may already be familiar with `[link](url)` and `![image](url)` syntax. We have expanded this to include a third `$[variable](text)` syntax. All three of these syntaxes now share a common set of features:
+
+{{varSyntaxTable
+| syntax | description |
+|:-------|-------------|
+| `[var]:content`  | Assigns a variable (must start on a line by itself, and ends at the next blank line) |
+| `[var](content)` | Assigns a variable and outputs it (can be inline) |
+| `[var]`  | Outputs the variable contents as a link, if formatted as a valid link |
+| `![var]` | Outputs as an image, if formatted as a valid image                    |
+| `$[var]` | Outputs as Markdown                                          |
+| `$[var1 + var2 - 2 * var3]` | Performs math operations and outputs result if all variables are valid numbers                                     |
+}}
+
+}}
