 ## Usage
 A simple usage example:<br/>
 ```bash
-cgrep --func --var --regex nam ./cgrep.cpp
+cgrep --func --var --regex n[aA]m ./cgrep.cpp
 ```
 Pleade do note that the regex will pass through both C++ and the regex engine, so if you would want to escape `\`, the regex you pass as the commandline arg would be `\\\\` instead of the normal `\\`.<br/>
