Follow the installation steps.
Go to Project > Properties > Compiler Options and add haxor library in it.
Haxor should be available on your Project References.
Haxor uses a different entry point than Haxe.
Using the created Main class make it extend Application.
The Application class wraps the initialization process and separate it in Load and Initialize
Using the Asset class, it is possible to preload different types of data.
The Application class automatically handles the queue and calls Initialize after everything is loaded.
In order to inform which Application class must be instantiated, the class pah must be passed in the script tag in the HTML
Using the application attribute you can select different entry point paths for your project.
The other attributes in the tag are temporary and will be handled differently in future versions.
This sums up a basic setup to use Haxor.
