Hey, I'm a PM contributing to the Paketo project. This is great feedback and something that we'll definitely work on improving on the website. I totally get that it's difficult to understand this content if you're not too familiar with Cloud Native Buildpacks.
In the meantime, are there any questions about Buildpacks and/or the Paketo project that we could help clarify? If you're interested in learning more about the buildpack architecture I'd suggest watching this Cloud Native Buildpacks intro talk that explains things pretty well - https://www.youtube.com/watch?v=SK6e_ZatOaw
