 ### How to use the language
 
 You can transpile Chookspeak to Javascript and HTML by using the program in the repository. Compile it with `gradle installDist`, then run `./build/install/chookspeak/bin/chookspeak` (add .bat if you're a crazy Windows user). You'll notice it complains about not having a file. Add the path as your argument. eg `./build/install/chookspeak/bin/chookspeak notepad.chsp`. Your program should be compiled to HTML and Javascript in valid egg format, which can be added to your Chookchat instance.
