+## Macros (Experimental)
+
+As you might (not) have noticed, *wenyan-lang* strives to be more readable (for ancient Chinese people). **Macros** provide syntactic sugars to bring the 文采 of your code to the next level.
+
+E.g. Now you can patch wenyan-lang's notorius print function like so:
+
+```
+或云「「書「甲」焉」」。
+蓋謂「「吾有一言。曰「甲」。書之」」。
+
+書「「問天地好在」」焉。
+```
+
+Since we're beating JavaScript to macros, here is a rough C equivalence:
+
+```
+#define   書(甲)焉   吾有一言。曰甲。書之
+書("問天地好在")焉。
+```
+
+See [**Full Documation**](https://github.com/LingDong-/wenyan-lang/blob/master/documentation/Macros.md), #440 for more details.
