-## Installation

-There are two ways to install this project from source, which depend on the version of the [go](https://golang.org/) version you're using.

-If you just need the binaries you can find them upon the [project release page](https://github.com/skx/math-compiler/releases).

-### Source Installation go <=  1.11
 
-If you're using `go` before 1.11 then the following command should fetch/update the project and install it upon your system:

-    git clone https://github.com/skx/math-compiler
-    cd math-compiler

 ## Possible Expansion?
 
 The obvious thing to improve in this compiler is to add support for more operations.  At the moment support for the most obvious/common operations is present, but perhaps more functions could be added.
