 hxcpp is the runtime support for the c++ backend of the [haxe](http://haxe.org/) compiler. This contains the headers, libraries and support code required to generate a fully compiled executable from haxe code.
 
+## Installing from haxelib
 
-# building the tools
+```sh
+haxelib install hxcpp
+```
+
+## Installing from git
 
+```sh
+haxelib git hxcpp https:/HaxeFoundation/hxcpp

-cd ${REPO}/tools/run
-haxe compile.hxml
-cd ${REPO}/tools/hxcpp

+Alternatively, if you plan on modifying hxcpp for development, you can clone manually and use `haxelib dev`:
+
+```sh
+git clone https:/HaxeFoundation/hxcpp
+haxelib dev hxcpp ./hxcpp
