 === Parameters ===
 An expression can refer to [[parameters:|project parameters]] that are evaluated to text or number constants prior to calculating the expression. Parameter names in expressions are wrapped in curly brackets and are case-sensitive. E.g. {File name}, {Ratio}.
+=== Comments ===
+Expressions can be annotated (commented). Any text between a double-slash (%%//%%) and the end of line is considered a comment and is ignored during expression evaluation. A comment can't span several lines. Example:
+<code>
+//Converted amount.
+[Amount] * {FX Rate}  // Using a parameter for the exchange rate.
+</code>
