-# The Bisquit Programming Language
-
-Bisquit is a first attempt at designing and implementing a simple, interpreted language; Drawing inspiration from typical assembly languages and BASIC.
-For a quick tour of the language, check the PDF in the /doc/ directory, and check out the the supplied example programs.
-
-To build the interpreter, go to the root of the project directory and do:
-
-    mkdir build && cd build
-    cmake ..
-    make
-  
-The bisquit_interpreter executable will then be built.
