I wasn't able to figure it out. The docs [1] have absolutely no information or overview on how the tool works, or how you should get started with creating a simple installer. Besides setup instructions, it only has details on individual sub components, beginning with with "Burn bundles". All linked tutorials are for previous versions of WiX. Is the expected workflow that I read a v3 tutorial and then read the "v4 for v3 users" article (which immediately leaves me discouraged with "A lot about WiX has changed between v3 and v4"), or that I immediately purchase enterprise support?
