+
+To enable this feature, you need to give ```ditaa``` an option ```-L``` or ```--latex```.
+
+##### Limitations
+
+* This feature is only available when you are generating ```.png``` files. [Issue-44](https://github.com/stathissideris/ditaa/issues/44)
+* Generally, LaTeX formulae are rendered narrower than the widths they occupy in ascii arts. You will sometimes see blanks after your formulae, especially when they are complicated ones, and there is no workaround to adjust this as of now. To mitigate this, you need to wait for [Issue-34](https://github.com/stathissideris/ditaa/issues/34)
