Build and Install LuneOS
For an easy life, develop on Linux. Ubuntu 12.04 LTS 64-bit works well.
Instructions for building (or just downloading) and installing an image can be reached by selecting a target device from the Devices page. Notice that there is a LuneOS VirtualBox Emulator which you can use instead of a target device.

Set-up is automated
$ wget https://raw.github.com/webOS-ports/webos-ports-setup/testing/Makefile $ make setup-webos-ports

You bitbake a "recipe". This is a simple text file of metadata with the extension .bb indicating how to fetch, build and install something. The system is very modular. One recipe depends on another and there are hundreds of recipes involved in our build.
The particularly interesting recipes for our purposes, such as
webos-ports-dev-package, are in
Repository Layout might make some sense to you now!
The Porting Guide sheds quite a lot of light on this too.
If you have made a worthwhile change, our Submitting Contributions instructions tell you how to get it pulled into the main line.
